The Foundations And Concepts of Islam
He describes it as that which guides to uprightness when He says,
"Verily, this Qur'aan guides to that which is most just and right."
The Qur'aan guides mankind to the most righteous path in all aspects of their life.
Whoever reflects on how the Qur'aan was revealed and how it was preserved will give the book its due estimation and purify his intention for Allaah alone. Allaah, the Exalted says,
"And truly, this (the Qur'aan) is a revelation from the Lord of all the worlds, which, the trustworthy spirit (Jibreel) has brought down upon your heart (O Muhammad) that you may be (one) of the warners."
So the One Who revealed the Qur'aan is Allaah, Lord of all the worlds; and the one who brought it is the trustworthy spirit Gabriel; and the one in whose heart it was revealed is the Prophet.
The Qur'aan is an everlasting miracle for Muhammad. It contains signs that shall abide till the Day of Resurrection. The signs and miracles of previous Prophets used to end at the termination of the Prophets' lives, but Allaah has made the Qur'aan the everlasting proof.
It is the extensive proof and dazzling sign. Allaah challenges the mankind to produce the like thereof or ten soorahs like it or even a single soorah that resembles it, and they are unable to do that in spite of the fact that it is composed of letters and words and the people on whom it was first revealed were people of eloquence and rhetoric. Allaah says,
"Or do they say: (Muhammad) has forged it? Say: Bring then a Soorah like unto it and call upon whomsoever you can besides Allaah, if you are truthful."
Among the things that testify to the fact that the Qur'aan is a revelation from Allaah is that it contains stories of the past nations, prophesied future events that came to happen as it has prophesied and the fact that it mentions many scientific facts that have not been discovered until recently. Another proof of its being a Divinely revealed Book is that the Prophet on whom it was revealed was unknown with anything similar to that or reported to have known anything similar to the Qur'aan. Allaah says,
