Was Muhammad (PBBUH) the Author of the Quran?

The Islamic belief is that the Quran, the Holy Book of Islam, contains unaltered revelations from Allah to His Prophet Muhammad through Angel Gabriel. Although Muhammad (may the peace and blessings of Allah be upon him) was illiterate and did not possess any formal education in reading or writing, Muslims believe that he memorized and transmitted these revelations to his Companions who then recorded them. 

Therefore, Muhammad is considered a conduit for conveying the divine message rather than an author of the Quran. The style and content of the Quran are unique and inconsistent with the known Arabic literature of its time, which further supports this belief.
