And when there comes to them a Book from Allah, confirming what is with them,- although from of old they had prayed for victory against those without Faith,- when there comes to them that which they (should) have recognised, they refuse to believe in it but the curse of Allah is on those without Faith. (2:89 by YUSUFALI)
a book from Allah is Quran and this verse is pointed to the Jews,saying that Quran confirm what is with them.
what is with them is Torah.
Basic math will lead us that Muhammad say that Quran confirm the Torah!
Muslims nowadays can't accept the idea that Quran confirm the Torah,saying the Torah was corrupted days before Muhammad and the Quran came to correct the corruption of the scripts,is this verse can tolerate this?
lets do a logic exercise:
If Jews,in Muhammad days,had a corrupt script - the verse should say that Quran came to correct what is with them!!!
The verse say implicit that Quran came to confirm what Jews had - Torah!!!
There will be muslims who would say that the what is with them isn't about the Torah,the script but about the revelation of the prophets like what YUSUFALI translate in 2:41
And believe in what I reveal, confirming the revelation which is with you
The answer for that is in 2:91
When it is said to them, "Believe in what Allah Hath sent down, "they say, "We believe in what was sent down to us:" yet they reject all besides, even if it be Truth confirming what is with them.
In this verse the Jews say that they only believe in what was sent down to us ,that can't be interpreted elsewhere - Jews Believe only in Torah.
Muhammad say :even if it be Truth confirming what is with them.
So Muhammad say implicit that the Quran confirm the Torah!
