The Warsh Mus’haf, which I completed in 3 years, is among the rarest editions of the Qur’an in the Islamic world. I have also written six Mus’hafs in different textual variants, which were distributed across the Islamic world. I first wrote the Warsh, then Hafs, and then Duri for Africa and Sudan, and I wrote the Qalun for Libya.

The Saudi authorities also actively track down perverted copies of the Koran, as shown by this article: Makkah governor orders confiscation of fake Qur’an copies. Naturally, the action of merely human Muslims in tracking down “fakes” show that there’s NO divine preservation of the Koran.
