The Prophet Muhammad (peace be upon him) was physically incapable to write the Qur’an. History has him as an illetrate man who could not write anything more than his own name. How could he write a book?

2. Sincerity.

The Prophet (peace be upon him) was morally constrained to tell the truth about the origin of the Qur’an. He was noted to be so honest and trustworthy that even his enemies called him al-Amin (the trustworthy). Moreover, he suffered persecution, refused offers to compromise, and maintained his message for a period of twenty-three years. Historians of religion have to conclude that he was sincere.

3. Psychology.

6. Science.
The Qur’an draws attention to a wide range of physical phenomena in order to teach moral lessons. The statements were not meant to teach science. Yet modern scientists are amazed at the accuracy of these statements. For example, the Qur’an said things about the growth and development of the human embryo which could not be studied without the use of a microscope. Dr. Keith Moore was professor and chairman of the Department of Anatomy at the University of Toronto. After reviewing the Qur’anic statements he said: “I am amazed at the accuracy of these statements which were already made in the 7th century AD.” Such knowledge in the Qur’an points to God as its source.

7. Consistency.

8. Inimitability.
A unique feature of the Qur’an is that no one is able to produce a book that would match its beauty, eloquence and wisdom. The Qur’an itself challenges humankind to produce even a chapter like it. But no one has been able to do it.

These eight reasons together form a strong cumulative case in favor of the Qur’an’s divine origin. Hence Muslims can be confident that the belief of Islam, which is based on the Qur’an, is true.
