Our Prophet’s (Peace be upon him) greatest miracle is the Qur’an, which Allah revealed fourteen centuries ago as a guide for humanity and called everyone to obey to attain salvation:
“But it is nothing less than a Reminder to all the worlds.” (Surah al-Qalam: 52)
Since that time, the Qur’an’s language has been easily understandable by people of every era:
“We have made the Qur’an easy to remember.” (Surah al-Qamar: 22)
At the same time its excellent and incomparable literary style, as well as the superior wisdom it contains, are definite proofs that it is the Divine word. Many other miraculous aspects also attest that it is the word of Allah.
For example, some scientific facts could only be “discovered” with the aid of modern technology; but their essence was revealed in the Qur’an some 1,400 years ago. Since it was impossible to discover these facts scientifically when the Qur’an was being revealed, it is clear that the Qur’an is Allah’s word to humanity.
When the Qur’an was revealed in the seventh century, the Arabs had innumerable myths about what we would consider scientific matters.
Lacking the technology to investigate the universe and the world of nature, they believed in myths and legends passed down from generation to generation.
For example, they thought that the sky was held up by mountains: Earth was flat, and high mountains located on its two sides acted as columns supporting the vault of the heavens. All of these myths were eradicated with the coming of the Qur’an. For example, the verse reading “Allah is He Who raised up the heavens without any support…” (Surah al-Ra’d: 2) invalidated that particular superstition.
Important knowledge about this and many other matters unknown at that time are given in the Qur’an.
When it was sent down, human beings knew very little about astronomy, physics and biology. And yet it contained important knowledge about the creation of the universe and human beings, the components of the atmosphere, and the balance in nature.
Allah created the universe from nothing and knows all things.
The Qur’an, which has a plain and clear style that everyone can understand, was revealed so that people would read and understand it, know the Creator, and know how to serve Him. Allah then elucidated the verses with numerous examples and stories, for “We have not omitted anything from the Book” (Surah al-An’am: 38).
The Qur’an is perfect and thus contains much detailed knowledge about both worlds, which it explains in wise terms: “We have sent down to you a Book containing your Reminder. So will you not use your intellect?” (Surah al-Anbiya’: 10).
One of the Qur’an’s most important aspects is that its original text has remained intact since its revelation: “We have sent down the Reminder and We will preserve it” (Surah al-Hijr: 9). The scriptures revealed before the Qur’an were altered, for various people added, changed, or deleted certain parts. But when a revelation came to our Prophet (Peace be upon him), Allah miraculously enabled him to memorize it. Immediately afterwards, it was written down by the “recorders of revelation.” During Abu Bakr‘s (may Allah be pleased with him) reign, the Qur’an became one volume; during Uthman‘s (may Allah be pleased with him) reign, copies were made and sent to the major cities of the empire.
