Dr Jay Smith discusses the book that Dr Asma Hilali wrote on the Sana Palimpsest manuscripts.  He talks about the conclusions that she came up with by comparing it to todays Hafs Quran; she says that there are seventy variants in sixty three verses.  She also believes that it is a student text.  Jay says that that shuts down the idea of the preservation of the Quran which both Muslim and the Quran claim ( ie Sura 85: 21,22).  Then Jay and Al discuss some of the differences as examples.  Then they ask the question : Is the Quran perfectly preserved?
