A) Quran is surely the book which is saved word for word from as it was given to prophet Muhammad and as it is today. No change even in coma or full stop. Same for all sects/people ,all places, all times. It is the only divine book that is memorized from cover to cover by over millions of people even today. When prophet Muhammad was given a segment via angel Gabriel, he memorized it, and was written immediately by his companions and memorized by them and then recited out loud at least 5 times a day in prayers so if there was any mistake it could be caught right away by other memorizers. When it was compiled there was no dispute not even on any coma or on full stop .Today in the fasting month of Ramadan whole Quran is recited out loud in prayers and among the attendees are people from all the countries from Afghanistan to Zimbabwe in big mosques in big cities in USA and no one ever said that Imam read something he didn’t hear before .Quran means only Arabic text while its translations are called translation.
Quran challenges its readers to prove me wrong and even tells ways to do so. Says find in me contradictions because if it was man written then it would have many contradictions.
One point to be cleared is word Quran means Arabic text not its translation which is only called translation of Quran and not Quran!
