I will list some. The Qur'an is unique in its clarity and plainess and comprehensiveness, it is eloquent but not baroque, without either contradiction or "plot holes". Its use of repetition in multiple ways is so perfect that it cannot be deconstructed. It corrects the tampering with the Bible in way which restores its theology and narrative to coherence. Every prophet now is seen to preach the same God not apparently different gods and this is shown very smoothly in a way that is sensible. Listed prophets are now seen to come to all peoples not just Jews as coincides with the fact that there were prophets before there were Jews. Everything about the Qur'an breathes honesty and forthrightness.
