Al Fadi and Dr David continue to disprove the myth of the perfect preservation of the Quran. In this episode they go to a book called Fadaelle Al Quran; in Sura 33 there is only 73 verses left of 200 original verses; the reason is that a sheep ate it according to Ayesha who had the only copy of the sura. According to Muslims the Quran was preserved by memory. in Sura 87: 6,7 Allah allows Mohammad to forget some suras that He wills. In Hadith Al Bukhari 50:38,39 Mohammad claims that Allah caused him to forget some verses.
