Further, the Holy Qur’an in several of its passages has referred to a number of scientific truths which were totally unknown in that age and centuries later attention of research scholars was drawn to them.

Such reference include the question of rotation of the earth (Naml, verse 90), existence of male and female cells in plaints (Taha, verse 35), existence of two contradictory forces within all particles, i.e., composition of atoms of negatively charged electrons and positively charged protons (Zariyat verse 29) and the law of gravitation (Ra'd, verse 2).

For these reasons it must be admitted that this Book, which is the eternal miracle of the 'Prophet of Islam, is not the product of any human brain. It is the word of Allah, which descended into the heart of the Holy Prophet from the metaphysical world. That is why the Holy Qur’an, in a number of passages, has challenged the unbelievers to produce a book similar to it. Though the diehard opponents of the Holy Prophet (S) tried their best, they could not succeed.

The Holy Qur’an expressly say: "Say: Surely if all men and jinn combined to bring the like of this Holy Qur’an, they would not be able to do so, even if some of them were to back the others." (17:88) This challenge of the Holy Qur’an still holds good. The Holy Qur’an, still throws a challenge to all the intellectuals of the world to bring a like of it, if they doubt its divinity. Their failure to accept the challenge is living evidence of the inimitability of the Holy Qur’an.

The Qur’an is Unaltered The Holy Qur’an is a book which preserves its original form and remains unaltered, because its special style and composition are such that nothing can be added to it nor anything can be deducted from it. If such an attempt is made by anyone, it would before long be detected.

Moreover, a large number of the companions of the Holy Prophet (S) from the very beginning of the descent of the Holy Qur’an put all its verses to writing so that they may remain immune from any alteration or change. The names of these persons are recorded in history and they are known as scribes of the revelation. Imam ‘Ali (A) is one of the most outstanding amongst them.

Further, it is historically well known fact that hundreds of persons during the Prophet's time and thousands in the following centuries learned the whole Qur’an by heart and recited it to the people on all occasions. Such people are called Huffaz. (memorizers of the Holy Qur’an).
