It is not for any human to whom Allah has given the Book and wisdom and Prophethood, that he should afterwards say to the people, “Leave (the worship of) Allah and be my worshippers” – but he will surely say, “Be sincere worshippers of Allah, because you teach the Book and you preach from it.”

And this is how We explain Our verses in different ways that they (the disbelievers) may say to you, (O dear Prophet Mohammed – peace and blessings be upon him), “You have studied” – and to make it clear for the people of knowledge.

For you (the disbelievers) may say, “The Book was sent down only to two groups (Jews and Christians) before us; and we were totally unaware of what they read and taught.”

And after them in their place, came those unworthy successors who inherited the Books – they accept the goods of this world (as bribes) and say, “We shall soon be forgiven”; and if similar goods come to them again, they would accept it; was not the covenant taken from them in the Book, that they must not relate anything to Allah except the truth, and they have studied it? And indeed the abode of the Hereafter is better for the pious; so do you not have sense?

And We did not give them any Books which they may read, nor did We send to them any Herald of Warning before you.
