I think it's clear that your understanding of islamist history is lacking. The Koran was clearly not the same original book under all caliphs. For that matter, there is no such thing as an "original" Koran.All that writing and you wasted your time. You don't teach us our history we have our history on Islam. The Koran was the same original book under all Caliphs
No you don't have the right history at all. Where are you getting this from? The Caliphs all had the same Koran and every Muslim had the same Koran
Did Allah tell you that?
