The vital importance of this book trumps any flaws that it may have...
While there are some errors in regards to abrogated verses... e.g. saying that verse 9:60 is abrogated by verse 6:63, an earlier verse... the fact that this Qur'an is put into reverse chronological order trumps any of these errors.
It is vitally important that non-Muslims understand Abrogation(naskh) as it pertains to the Quran. Verses that were revealed chronologically later, abrogate, or nullify and replace, any earlier verse that is contradictory. In other words, all peaceful verses of the Qur'an have been nullified, and replaced by the verses commanding violence against non-Muslims, and the ultimate genocide of all non-Muslims.
The chapters of the Qur'an have been deliberately mis-arranged by Muslims in an effort to encrypt the Qur'an, in order to prevent non-Muslims from understanding the danger that Islam presents to all non-Muslims. By placing the chapters of the Qur'an into reverse chronological order, non-Muslims can clearly and easily see which verses of the Qur'an are valid, and which are null and void without having to consult abrogation charts or shuffle though the deliberately encrypted Qur'an. The valid chapters of the Quran are presented first and the invalid chapters are presented later.
The vital importance of this book trumps any flaws that it may have.
We non-Muslims can no longer afford to remain ignorant of Islam, and this book goes a long way towards educating non-Muslims about the true nature of Islam.
