And for a similar purpose (of confirming and testifying to the truth of all previous Scriptures) have We sent down to you this perfect Book. And those whom We have given (the true knowledge of) the Book (Torah) believe in it and of these (Makkans who possessed no sacred Scriptures before) there are some who believe in it (- the Qur'ân). And it is only the ungrateful (disbelievers) who deny Our revelations deliberately and persistently.
