From Refutation of the Scroll to Isra and Mi'raj

Dawah to the Tribes During the Sacred Months

During these three consecutive years, when the Quraysh had imposed a boycott on Muhammad and besieged the Muslims, Muhammad and his family and companions sought refuge in a valley near Mecca called "Shi'b Abi Talib". They suffered various hardships during this period, including food shortages at times.

The Prophet Muhammad and the Muslims were not allowed to interact with people or speak to them except during the sacred months when Arabs from different tribes came to Mecca for pilgrimage and trade. During these sacred months, conflicts and hostilities were set aside, and there was no killing, punishment, aggression, or revenge allowed. In these months, Muhammad would go out to the visiting tribes, inviting them to the religion of Allah, delivering good news of its rewards, and warning them of its consequences.

Muhammad endured a great deal of harm and hardship during this period because of his mission. However, his perseverance in the face of the siege earned him the sympathy and support of many people, especially those whose hearts had not been hardened like those of Abu Jahl, Abu Lahab, and their likes.

The Siege of Muslims in Al-Shu'ab

Despite the passage of time and the numerous hardships suffered by the Muslims at the hands of the Quraysh, who were their own brothers, in-laws, and relatives, many of them began to feel the severity of the injustices and cruelty committed against them. Had it not been for certain individuals in Mecca who showed compassion for the Muslims, they would have perished from hunger. Some Meccans would bring camels laden with food or goods during the night to alleviate the hunger of the Muslims. They would loosen the camel's reins and tap on its sides so that it would enter the encampment and provide sustenance to them.

As the hardships endured by Muhammad, his family, and his companions became increasingly intolerable, he approached Zuhayr ibn Abi Umayyah, whose mother was Atika bint Abdul Muttalib. Muhammad said to Zuhayr, "Wouldn't you be pleased to eat, wear fine clothes, and marry women, while your cousins are left without anyone buying from them or selling to them, and they can neither marry nor be married to? I swear by Allah that if they were cousins of Abu al-Hakam ibn Hisham (Abu Jahl) and I invited him to a similar arrangement, he would never have refused me". Zuhayr and another man agreed to violate the boycott agreement secretly with the help of others they could persuade.

They reached a consensus, and the five men agreed to work on nullifying the boycott agreement. The following day, Zuhayr circumambulated the Kaaba seven times, then called out to the people, "O people of Mecca! Should we eat food, wear clothes, and marry women while the Banu Hashim are perishing, unable to buy or sell? By Allah, I will not sit until this oppressive document is torn apart!" Abu Jahl barely heard him when he shouted back, "You lie! By Allah, it will never be torn!" Zuhayr was joined by Zama'a ibn al-Aswad and Abu al-Bakhtari ibn Hisham, and they all accused Abu Jahl of lying and supported Zuhayr. Abu Jahl realized that the situation had been resolved overnight, that the people had agreed upon it, and that opposing them would only lead to trouble. Fearing the consequences, he relented.

The man tasked with tearing the document, Mu'tam ibn 'Adi, found that it had been devoured by termites, except for the phrase "In Your Name, O Allah". This provided an opportunity for Muhammad and his companions to return to Mecca, engage in trade with the Quraysh, and negotiate with them while both parties remained cautious and ready for any future conflicts.

The Infallibility of Muhammad in Conveying

Some biographical accounts suggest that those who participated in nullifying the boycott agreement, most of whom were still idol worshippers, approached Muhammad with a request to reconcile with the Quraysh in order to prevent further harm. They proposed that Muhammad acknowledge their idols, even if only by pointing to them with the tip of his finger. Muhammad inclined towards considering some form of agreement with them out of kindness, saying to himself, "I have nothing to lose if I do it, and Allah knows that I am a man of integrity".

Alternatively, in another narrative, it is mentioned that those who nullified the boycott agreement and a group with them approached Muhammad during the night and showed him great respect and humility. They praised him, saying, "You are our master, O our master". They continued to approach him, trying to persuade him, and he nearly acceded to some of their requests.

These two narratives are based on the accounts of Sa'id ibn Jubayr in the first one and Qatadah in the second. They both attribute these events to the context of nullifying the boycott agreement. However, the exact historical context and events leading to the revelation of the mentioned verses remain subject to debate.

Regardless of the specific historical context, the truth that remains uncontested is the psychological greatness of Muhammad, as depicted in these accounts. They illustrate his sincerity and acknowledgment of the potential for human error. When the revelation came, it alerted him to his actions, both regarding the incident with the blind man and the potential temptation to compromise his message to please others. Muhammad's commitment to conveying the revelation to the people was unwavering and unaffected by pride or ego. He humbly accepted his role as a human being who could err but remained steadfast in delivering the message of his Lord.

In reality, acknowledging the potential to falter is not something readily admitted by most people, especially those of great stature. What sets such individuals apart is their willingness to hold themselves accountable, even if it is a challenging self-assessment. The elevated nature of prophethood allows the soul to rise above mere greatness, revealing the complete truth, and this truth was manifested in Muhammad's unwavering commitment to conveying the message of Allah.

The Death of Abu Talib and Khadijah

Muhammad, along with his followers, continued to spread his message in Mecca and among the tribes that gathered during the holy months despite the challenges posed by the Quraysh. Despite the widespread knowledge of Muhammad's message among the Arab tribes and the growing number of followers, neither Muhammad nor his companions were spared from the persecution of the Quraysh. Muhammad was unable to provide full protection to his followers.

Within a short span after the nullification of the boycott agreement, Muhammad faced two significant tragedies in a single year— the deaths of Abu Talib and Khadijah. At the time, Abu Talib was over eighty years old. When he fell seriously ill, and it was clear that he was nearing the end of his life, the Quraysh were concerned about what might happen between them and Muhammad and his followers after Abu Talib's passing. They were particularly worried about Hamza and Umar, who were known for their strong and aggressive support of Islam. So, the notables of Mecca went to Abu Talib and said to him, "O Abu Talib, you are aware of our situation, and you know what lies ahead between us and your nephew. We propose a solution: ask him to give up his religion, and in return, we will give him whatever he wants. Let him leave our religion, and we will leave his. Let him and his religion be, and we will do the same".

Muhammad and the leaders of the Quraysh gathered in the presence of Abu Talib. When Muhammad understood their proposal, he responded, "You want me to say a single sentence that will make you rulers of all the Arabs and the Persians obey you?" Abu Jahl replied, "Yes, and your father and your mother". Muhammad then said, "You say: 'There is no god but Allah,' and you renounce everything you worship besides Him". Some of them exclaimed, "Do you want, O Muhammad, to make all our gods into one god?" Then, some of them said to others, "By Allah, this man is not giving you what you want". They left, and after some time, Abu Talib passed away.

Khadijah, who had been Muhammad's pillar of support with her love, loyalty, gentleness, and purity of heart, also passed away. She had made Muhammad's mission easier to bear, lightening his burden with her patience. Her loss was deeply felt, leaving Muhammad with profound sorrow.

These two painful events, the deaths of Abu Talib and Khadijah, had a significant impact on Muhammad. They were trials that tested his resolve and determination. Yet, he remained steadfast in his mission despite the emotional and social challenges they presented.

Quraysh Increases Its Harm

After losing both Abu Talib and Khadijah, Muhammad saw that the Quraysh were intensifying their persecution of him. One of the incidents that exemplified this was when a simpleton from the Quraysh threw dirt at him, hitting him in the head. Muhammad entered his house with the dirt still on his head. His daughter, Fatimah, came to him and began to remove the dirt while crying.

Few things are more painful than hearing the cries of our children and, even more so, the cries of our daughters. Every tear that falls from the eyes of a daughter feels like a heavy drop of molten lead, falling on our hearts and causing us immense distress. The anguish is so profound that it almost makes us speechless due to the intensity of the pain. Every sigh of sadness stirs up moans deep in our hearts and livers, and they are the harshest of all. They choke our throats, and tears almost flow from our eyes.

Muhammad was a loving father to his daughters, and he was exceptionally compassionate towards them. So, what did he do when he saw his daughter crying, especially when her tears were for what had happened to her father? He turned his heart towards God and reaffirmed his faith in God's help. He said to his daughter, as tears welled up in her eyes, "Do not cry, my dear! God is my protector". Then he repeated:

"By Allah, Quraysh had not harmed me so much as they did when Abu Talib died".

Muhammad's Journey to Taif in 628 CE

After facing increasing hostility from the Quraysh, Muhammad found himself in a difficult situation. He decided to leave for Taif, hoping to seek support and perhaps find allies among the Thaqif tribe. He left on this journey alone and kept it a secret from everyone, hoping to bring the Thaqif to Islam. However, he returned from Taif with a bitter response. The Thaqif leaders decided not to mention his visit so as not to anger their own people.

Muhammad had hoped that the Thaqif tribe might provide him with the support and protection he needed, but he was met with harsh rejection. Instead of finding allies, he faced further opposition and even mockery from some of their foolish leaders. They insulted him and hurled abuses at him. Distressed by their response, Muhammad sought refuge near the wall of Al-Ta'if, where he was approached by the sons of Rabi'ah, Sheibah, and Utbah, who offered him shelter.

As he sat under the shade of a grapevine, Muhammad, burdened by sorrow and pain, raised his head to the sky, supplicating to God with a heart full of complaints and anguish. He said: "O Allah, to You alone, I complain my weakness, my scarcity of resources, and my lowliness before people. You are the Most Merciful of the merciful. You are the Lord of the oppressed, and You are my Lord. To whom do You entrust me? To some distant stranger who will frown at me, or to an enemy to whom You have given control over my affair? As long as you are not angry with me, I will not care. Your favor is of a more expansive relief to me. I seek refuge in the light of Your countenance by which all darkness is dispelled, and both this life and the life to come are put in their right course against incurring Your wrath or being the subject of Your anger. To You, I submit until I earn Your pleasure. Everything is powerless without your support".

The two sons of Rabi'ah were moved by his words and felt compassion for him due to the difficulties he had faced. They sent their Christian servant, Addas, to offer him some grapes from the vineyard. When Muhammad reached out to take the grapes, he said, "In the name of Allah," before eating them. This act puzzled Addas, who asked about Muhammad's background and faith. Upon learning that Muhammad was a prophet and that his brother was a prophet too (referring to Jonah), Addas kissed Muhammad's forehead, his hands, and his feet, moved by the message of Islam. Sheibah and Utbah's sons were surprised by what they saw and heard and commented, "O Addas, no one from this land has ever done what you have done!" However, this encounter did not lead them to abandon their faith; they acknowledged Muhammad's virtue.

Muhammad Presents Himself to the Tribes

Despite the increased hostility he faced from the Quraysh, Muhammad did not waver in his mission to spread the message of Islam. He began to present himself to various Arab tribes during the pilgrimage seasons, inviting them to embrace the truth and informing them that he was a Prophet sent by God. He asked them to believe in him, but his efforts were met with mixed responses.

However, Muhammad's uncle, Abu Lahab (Abdul-Uzza ibn Abdul-Muttalib), actively opposed him and followed him wherever he went, urging people not to listen to him. This opposition from his own family members added to the challenges Muhammad faced.

Muhammad did not limit his outreach to the tribes during the pilgrimage seasons in Mecca. He also visited towns like Kindah, Kutha, Banu Hanifa, and Banu Amir ibn Sa'sa'a, seeking their support and presenting his message to them. Unfortunately, he received no positive response from these tribes, and they rejected his message.

The tribes' reasons for rejecting Muhammad varied. Some, like Banu Amir, were hoping for political advantage and thought that if they supported Muhammad and he succeeded, they would gain power. When Muhammad told them that the matter was ultimately in God's hands, they lost interest and rejected him.

The reasons for these tribes' rejection of Muhammad were complex and not solely rooted in religious beliefs. Economic considerations, political aspirations, and local customs played a significant role in their decisions. For example, the city of Taif was a prominent destination for the people of Mecca during the summer because of its pleasant climate and vineyards. The people of Taif also had their own idol and a temple they revered. If the Thaqif tribe had accepted Muhammad's message, it would have disrupted their economic interests and created enmity between them and the Quraysh, which they wished to avoid.

In essence, the tribes' rejection of Muhammad was driven by a mix of religious, economic, and political factors, and it mirrored the resistance he faced in Mecca from the Quraysh.

Muhammad Proposes to Aisha and Marries Sauda

Muhammad's decision to marry after the death of Khadijah was a practical one. He was seeking companionship and support in the wake of her loss. He proposed to Aisha, the daughter of his close friend Abu Bakr, when she was still a child, around seven years old. The marriage contract was formalized but consummated when Aisha was approximately nine years old.

It's important to note that cultural and societal norms regarding marriage were different during that time, and marrying at a young age was not uncommon. Marriages were often arranged for various reasons, including strengthening social bonds and alliances.

In addition to his marriage to Aisha, Muhammad also married Sauda bint Zam'a, a widow of one of the early Muslim emigrants to Abyssinia who had returned to Mecca and passed away there. Muhammad's marriages served multiple purposes, including providing care and support for widows and orphans, strengthening ties with his companions, and setting an example for the Muslim community regarding marriage and family life.

It's essential to approach historical practices and customs from that era with an understanding of the context and cultural norms of the time while recognizing that contemporary standards and values have evolved over the centuries.

The Isra and Mi'raj Year (621 CE)

During this period, the Isra and Mi'raj (the Night Journey and Ascension) took place. Muhammad's Isra (Night Journey) occurred while he was in the house of his cousin Umm Hani, the daughter of Abu Talib. Umm Hani's given name was Hind. She later recounted, "The Messenger of Allah spent that night at my house, and he performed the last Isha prayer. After that, he slept, and we all slept. When it was just before dawn, the Messenger of Allah woke up, and when he offered the Fajr (morning) prayer, he asked me, 'O Umm Hani, I prayed Isha with you and then went to the Masjid al-Aqsa (in Jerusalem) and prayed there. Now, I have just prayed the Fajr prayer with you. Tell the people about this, and they will deny it and harm you.' I replied, 'O Prophet of Allah, don't inform the people about it, for they will disbelieve you and harm you.' He said, 'By Allah, I will inform them about it.'"

Isra and Mi'raj: With the Body or the Spirit?

Those who argue that the Isra and Mi'raj were solely a spiritual experience for Muhammad, may peace be upon him, rely on this narration and what Aisha used to say: "The body of the Messenger of Allah did not disappear, but Allah took his spirit". Muawiya ibn Abi Sufyan, when asked about the night journey of the Prophet, would say: "It was a true vision from Allah". They also cite the following Quranic verse as evidence: "And We did not make the sight which We showed you but as a trial for the people.".. (Quran, Surah Al-Isra, 17:60).

On the other hand, some argue that the Isra from Mecca to Jerusalem was a physical journey, citing Muhammad's mention of what he observed during the journey in the desert, which will be explained later. They also argue that the Mi'raj to the heavens was a spiritual experience. There are differing opinions on this matter, and scholars have engaged in extensive debates, with thousands of articles and papers written on the subject. Before expressing our perspective on the wisdom of the Isra and Mi'raj, we need to narrate the story in accordance with what is found in the biographical sources.

The Depiction of Al-Isra in Biography Books

The narrative of the orientalist Dur Manjam in this story is extracted from various biography books in a splendid narrative. Here is its translation:

In the middle of a night filled with the utmost serenity, the night birds fell silent, and the twinkling stars ceased their shimmer. The rustling of leaves came to a halt. Suddenly, Muhammad awoke to a voice calling out, 'O sleeper, arise.' He rose and found himself face to face with the Angel Gabriel. Gabriel had a radiant forehead, a snow-white face, and golden hair that shone. He stood adorned in garments embellished with pearls and gold. Multicolored wings quivered around him, and in his hand was a miraculous creature known as Al-Buraq. It had wings resembling those of an eagle, which bowed before the Prophet, and with a swift leap, they soared above the mountains of Mecca and the sands of the desert, heading north. The angel accompanied him on this journey, pausing at Mount Sinai, where God spoke to Moses. They stopped again in Bethlehem, where Jesus was born, and then they ascended into the air. Whispering voices attempted to halt the Prophet, but he continued, firmly believing that none but God could deter his mount. They reached the Holy Land, where Muhammad tied Al-Buraq and offered prayers amidst the ruins of Solomon's Temple, joined by Abraham, Moses, and Jesus.

Then came the Ascension, and Muhammad ascended upon a rock associated with Jacob. From there, he ascended swiftly through the heavens. The first heaven was made of pure silver, with stars suspended by golden chains. On each chain, an angel stood guard, preventing demons from reaching the heavens or the jinn from hearing the celestial secrets. In this heaven, Muhammad greeted Adam, and all the creatures therein praised their Lord. Muhammad encountered Noah, Aaron, Moses, Abraham, David, Solomon, Enoch, John, and Jesus in the subsequent heavens. He also saw Azrael, the Angel of Death, whose size was such that the distance between his eyes was a journey of seventy thousand days. Under his authority were one hundred thousand detachments, and he maintained a colossal book listing the names of those born and those who died. Muhammad also beheld the Angel of Tears, weeping over the sins of humanity, and the Angel of Retribution with a coppery face, responsible for the element of fire, seated upon a throne of flames. There was also a massive angel, half of fire and half of ice, surrounded by a host of angels ceaselessly glorifying God. In the seventh heaven resided the angels of justice, overseen by a king larger than the entire Earth, with seventy thousand heads, each head possessing seventy thousand mouths, each mouth speaking seventy thousand languages, each language having seventy thousand dialects—all praising and sanctifying God".

While contemplating this wondrous creation, Muhammad ascended to the Sidrat al-Muntaha, where he was met by the presence of innumerable angelic beings to the right of the Throne. In an instant, he crossed vast oceans, regions of light and darkness, and millions of veils of darkness, fire, water, air, and space. Each of these veils spanned five hundred years' journey. He surpassed the veils of beauty, perfection, secrets, majesty, and unity. Seventy thousand detachments of angels stood behind them, prostrating without moving or uttering a word".

Then, Muhammad felt himself ascend to the abode of the Almighty, where he was filled with awe. Earth and sky converged until they were almost indistinguishable, as if they had been swallowed by annihilation, leaving only the size of a sesame seed in a vast expanse. Surely, this is how a human should be in the presence of the King of the universe".

In the presence of the Throne, Muhammad, who was as close as two bows' length, or even closer, bore witness to God with his own eyes. He saw things beyond the scope of human language, transcending all comprehension. The Almighty extended His hands upon Muhammad's chest and shoulder, and Muhammad felt himself ascend to the ultimate pinnacle of spiritual serenity and surrender".

After a conversation not recorded in the meticulously authenticated books of tradition, God commanded His servant to establish fifty daily prayers for every Muslim. When Muhammad descended and met Moses, Moses questioned him about this command".

'How do you expect your followers to pray fifty times a day?' Moses asked. 'I have experience with people before you, and I tried every means with the Children of Israel to lessen their burdens. Trust me, go back to your Lord and request a reduction in the number of prayers.'

"Muhammad returned to God multiple times, and each time, the number of prayers was reduced until it reached five. Moses encouraged Muhammad to return once more, but Muhammad was hesitant. Thus, the five daily prayers were established".

Gabriel then accompanied the Prophet to visit the Paradise prepared for the righteous after resurrection. Afterward, Muhammad returned to Mecca, where he unfastened Al-Buraq and dismounted".

This is the narrative of the orientalist Dur Manjam regarding the story of Al-Isra and Al-Mi'raj. You can find variations of this narrative scattered throughout many biography books, though differences in some aspects may exist. For example, Ibn Hisham's account attributes words to the Prophet after his meeting with Adam in the first heaven, which are not present in other accounts. Furthermore, you can find additional details in various sources, such as books of interpretation. It is within the right of historians to question the level of scrutiny and examination given to these accounts and what can be authentically attributed to the Prophet with a reliable chain of transmission.

If there is insufficient space here to delve into the discussion of the nature of Al-Isra and Al-Mi'raj—whether they were physical, spiritual, or a combination thereof—then it is important to note that there are diverse opinions among scholars, and there is no harm in holding one view over another. It is also within the rights of those who wish to explore the wisdom behind Al-Isra and Al-Mi'raj, if any, as it pertains to their understanding.

Al-Israa and the Unity of Existence

In the spiritual journey of Muhammad during Al-Israa and Al-Mi'raj, the meaning of transcendence reached the highest realms. It embodies a significance greater than what is often portrayed, sometimes mixed with the imaginative tales of speakers and preachers. In that extraordinary moment, the powerful spirit of Muhammad experienced the ultimate unity of existence. There were no veils of time, place, or other constraints that limit our human understanding in life. Everything dissolved before the vision of Muhammad, and the entire universe converged within his spirit. He was awakened from eternity to eternity, witnessing the evolution of unity to perfection through goodness, grace, beauty, and truth, triumphing over evil, deficiency, ugliness, and falsehood by the grace and forgiveness of God. Such spiritual elevation requires a power beyond human comprehension.

Subsequently, those who followed Muhammad, while unable to reach the same heights of his thought and the strength of his connection with the unity of the cosmos, faced no blame. Excellence varies among individuals, and some are gifted more than others. Achieving the truth is always subject to the limits that our capacities impose, which we cannot surpass.

By analogy, we may mention the story of the blind men who wanted to describe an elephant. One said it was a long rope because he touched its tail, another said it was thick like a tree trunk because he felt its leg, and so on. This analogy, relevant to our discussion, allows us to compare Muhammad's perception of the unity of the cosmos during Al-Israa and Al-Mi'raj to the first glimpse of the elephant, which allows us to view it in isolation from the rest of its being. Yet, it does not capture the full unity of the cosmos and the continuity of its existence from the beginning with Adam to the end on the Day of Resurrection, where the limits of place vanish entirely.

During the Israa of the spirit, as in the Israa and Mi'raj combined, we witness the sublime and the beautiful, the majestic and the powerful. It serves as a powerful representation of the spiritual unity from the dawn of existence to its eternity. This ascent, symbolized by the encounter with the mountain of Sinai where God spoke to Moses, and with Bethlehem where Jesus was born, along with the spiritual congregation that included Muhammad, Jesus, Moses, and Abraham in prayer, illustrates the unity of religious life as the foundation of the cosmic unity.

In our modern age, science acknowledges the Israa of the spirit and the Mi'raj of the soul. When sound waves can travel over the ether through radio, or when thoughts can be read and understood, we move beyond what was once considered the realm of imagination. The hidden forces in the universe continue to reveal themselves to our knowledge every day. When a spirit reaches the level of power and authority that Muhammad achieved, God takes him on a night journey from the Sacred Mosque to the Al-Aqsa Mosque, and this aligns with the advancements of our scientific understanding. The wisdom behind these powerful and sublime meanings, portrayed in the Israa and Mi'raj, lies in the unity of spiritual essence and the unity of the universe, as embodied within Muhammad's very being, presented explicitly for anyone who seeks to elevate themselves above the mundane illusions of life and strive to grasp the true essence of reality – understanding their place and the place of the entire world within it.

Doubt Among the Quraysh and the Apostasy of Some Believers

The Arabs of Mecca were unable to comprehend these profound meanings. When Muhammad informed them about the event of his Israa, they focused on the material aspects of this journey and questioned its feasibility. Doubts began to creep into the minds of his followers who believed in him. Many said, "By Allah, this is quite unbelievable! A month's journey from Mecca to Syria, and then he claims that Muhammad went on a night journey and returned to Mecca in a single night!?" This skepticism led some of those who had embraced Islam to apostatize.

Those who were troubled by doubt in this matter went to Abu Bakr and related the narration of Muhammad's journey to him. Abu Bakr responded, "You are accusing him of falsehood?" They affirmed, "Yes, he is in the mosque narrating it to the people". Abu Bakr declared, "By Allah, if he has indeed said it, he has spoken the truth. He informs me that news comes to him from God, descending from the heavens to the earth, in the span of a night or day. I believe him in something much farther than this". From that day forward, Muhammad conferred upon Abu Bakr the title of "As-Siddiq" (The Truthful).

Those who argue that the Israa was a physical journey support their viewpoint by suggesting that when the Quraysh, upon hearing of the Israa, questioned Muhammad about its details, he described a miraculous steed (Buraq) that he rode during the journey and how it was led to him. They assert that if the Israa were a spiritual experience, there would have been no need for such detailed accounts. They also argue that the two animals involved in the journey, a steed and a mule, bore witness to the truth of Muhammad's account when they confirmed his description to the Quraysh, validating what he had narrated.

Furthermore, some argue that if those who believe in the spiritual interpretation of the Israa had lived in our modern times, they might not have been as surprised by it. In our contemporary era, scientific advancements, such as telepathy and the ability to convey information across vast distances instantaneously, have expanded the realm of the possible beyond what was once considered imaginative. The forces that govern the universe continue to unveil new revelations to our understanding every day. Therefore, when a spirit possesses the strength and authority that Muhammad had, it is not beyond the realm of possibility for God to take him on a journey from the Sacred Mosque to Al-Aqsa Mosque and beyond, as science continues to redefine the boundaries of human perception and knowledge.
