It is an established and undeniable fact that the Prophet Muhammad, (peace and blessings be upon him) was unlettered. The Quran which was revealed to him has challenged all mankind with all their literary geniuses, non-Muslim scholars and scientists, from the first day of its revelation to the Last Day, to produce something like it.
There is no other book like it. It is absolutely perfect in the Arabic language. It has no mistakes in grammar, meanings or context. Moreover predictions in the Quran have come true; and its teachings are clearly for all people, all places and all times.
In this video Sheikh Sohaib Saeed brings to light verses from the Quran as evidence that the Quran is an absolutely formidable, extraordinary and unconquerable stronghold which the hand of heaven established on the earth.
