Like if Quran or Koraaan doesn't contradict the Torah...
If you are gonna to say that the differences are due because the Torah is corrupt, then why an omniscient god would suggest to Muhammad if he has any doubt about the revelations he was receveing he can go and to Christians and Jews, that rely on corrupt books.
That's the way a bad done "counterfeit dollar bill" sounds like.
It is He Who has sent down the Book (the Quran) to you (Muhammad SAW) with truth, confirming what came before it. And he sent down the Taurat (Torah) and the Injeel (Gospel).[3:3]
“And He (Allah) will teach him ['Iesa (Jesus)] the Book and Al-Hikmah (i.e. the Sunnah, the faultless speech of the Prophets, wisdom, etc.),(and) the Taurat (Torah) and the Injeel (Gospel).” 3:48
O people of the Scripture (Jews and Christians)! Why do you dispute about Ibrahim (Abraham), while the Taurat (Torah) and the Injeel (Gospel) were not revealed till after him? Have you then no sense?[ 3:65]
And if only they had acted according to the Taurat (Torah), the Injeel (Gospel), and what has (now) been sent down to them from their Lord (the Quran), they would surely have gotten provision from above them and from underneath their feet. There are from among them people who are on the right course, but many of them do evil deeds.[[5:66]
“And in their footsteps, We sent ‘Iesa (Jesus), son of Maryam (Mary), confirming the Taurat (Torah) that had come before him, and We gave him the Injeel (Gospel), in which was guidance and light and confirmation of the Taurat (Torah) that had come before it, a guidance and an admonition for Al-Muttaqun (the pious – see V.2:2).
Let the people of the Injeel (Gospel) judge by what Allah has revealed therein. And whosoever does not judge by what Allah has revealed (then) such (people) are the Fasiqun (the rebellious i.e. disobedient (of a lesser degree) to Allah.”[5:46-47]
If nothing else, these passages from the Qur'an confirm that Mohammad had a much greater appreciation for the Taurat and Injeel than bmz of Singapore has ever shown in this thread.
