Is there any narration from Taba'in or companion of Holy Prophet Muhammad (Sallallahu'alayhiwassalam) that proves that the Torah was texually corrupted or changed? When I say Torah, what I mean is the entire old testament or the Hebrew Bible. Are there any narration from taba'in or companion? Thanks!
Yes from Ibn Abbas (RA):
Sahih Al Bukhari Volume 9, Book 93, Number 613:
Ibn 'Abbaas said, "How can you ask the people of the Scriptures about their Books while you have Allah's Book (the Qur'an) which is the most recent of the Books revealed by Allah, and you read it in its pure undistorted form?"
Sahih Al Bukhari Volume 9, Book 93, Number 614:
Narrated 'Ubaidullah bin 'Abdullah:'Abdullah bin 'Abbaas said, "O the group of Muslims! How can you ask the people of the Scriptures about anything while your Book, which Allah has revealed to your Prophet contains the most recent news from Allah and is pure and not distorted? Allah has told you that the people of the Scriptures have changed some of Allah's Books and distorted it and wrote something with their own hands and said, 'This is from Allah, so as to have a minor gain for it. Won't the knowledge that has come to you stop you from asking them? No, by Allah, we have never seen a man from them asking you about that (the Book Al-Qur'an ) which has been revealed to you.
Note that the verse Ibn Abbas is referring to is Quran 2:79.
