A Concise Guide to the Quran
Answering Thirty Critical Questions
By Ayman S. Ibrahim · 2020
Many manuscripts of the Quran written throughout Muslim history, when compared to one another, reveal ample differences, scribal errors, and obvious variants. Simply stated, what many call the unchanged, inerrant copy of the Quran is actually a twentieth century project. Not surprisingly, the editorial board responsible for the 1924 project stated in the final copy that the project was a result of significant concerns among Muslims regarding “errors” in copies previously used in Egypt’s local schools. Nonetheless, most Muslims do not recognize this history and consider the 1924 Royal Cairo Edition of the Quran textus receptus (received text) that existed throughout Islamic history since Uthman. This copy has become the official Quran. -
You can read this book. Loofy and other moron moslems won't accept any evidence because in their hearts, their 1924 Cairo quran has been the same since the dinosaurs, let alone 7th century AD. They want to get into a debate where their arabic religion is the longest, best, strongest, most popular etc etc, regardless the facts.
