So both Torah and the Bible were somehow corrupted. So how do you(Muslims) know that the Quran isn’t corrupted. If God allowed for two of his scriptures to become corrupted why wouldn’t he allow the third one to be corrupted also? So if Quran cannot be corrupted and the Bible and the Torah just to contain teachings of Quran why didn’t God give the uncorruptable Quran to mankind in the first place? Why did He gave them the corruptable Torah and the Bible and then around 600 years after His failure to show the “true” teachings to people, which he forseen(He is God after all), He gave us the so-called truth and said that He made a mistake(not literal words probably) when He gave us the corruptable two books and now after so many years He gave us the uncorruptable book? Doesn’t make sense. So the argument follows:
P1: God’s word cannot be corrupted because Quran is supposly God’s word and Quran cannot be corrupted.
P2: Muslims aknowledge that the Bible and the Torah are God’s words so both these cannot be corrupted as Quran cannot be corrupted.
P3: The Bible and the Torah contradict Quran.
P4:The Bible and the Torah are older than Quran and God cannot contradict himself.
C1: Quran is therefore false.
Muslims could say that Quran can be corrupted and tear my argument apart, but then there would be the same chance that Quran is very different from the original form as there is with the Bible.
