The Islamic argument why the Quranic teachings are different to the Torah and the Bible is that “people corrupted” these books. Let us see:
1. The Quran was only put as one book 20 years after Muhammad died!! Before that, it was scattered as scrolls written on stones, leather, and bits of papers. Why Muhammad or Allah never asked for the book to be collated before Muhammad died! (I have another post about that)!
2. Of the four scribes (even the hadith cannot agree in their names!) Only one person survived to write it. How can we trust a no body by Zaid Ibn Tabith to remember 114 chapters with 6,350 verse in the correct order.
3. Too many repetitions that do not make sense until you realise Muhammad was getting old and forgetful as the authentic hadith says in multiple places:
Narrated Aisha: The Prophet heard a man reciting the Qur’an in the mosque and said, “May Allah bestow His Mercy on him, as he has reminded me of such-and-such Verses of such a Surah.”
Sahih Bukhari 6:61:556 / Sahih Muslim 4:1720
And Quran 87:6:
“We will have you recite ˹the Quran, O Prophet,˺ so you will not forget!”
Muhammad was forgetting what verses he said
4.Islamic source confirm that the caliph Uthman ordered various copies of the Qur’an to be burnt because there were clear differences in the Qur’ans among people of Sham and people of Iraq. The differences were so great Uthman and his companions feared future dispute. Uthman asked Hafsa for her copy and he ordered to make many copies and destroy all the other copies. This shows that memorization had failed to completely preserve the Qur’an.
5. The compilation of the Qur’an was clearly a human process involving trial and error, educated guesses, faulty memories, fallible opinions, disagreements, mistakes, ignorance, and bad decisions. And we can’t forget, of course, the pile of manuscripts reduced to ashes by Uthman in his desperate attempt to destroy all evidence that the Qur’an hadn’t been perfectly preserved.
Now you have the facts, can you really claim the Quran is perfect and not corrupted? Seriously?
