Recite thou that which hath been revealed unto thee of the Book and establish thou the prayer; verily prayer preventeth man from indecency and that which is disreputable: and surely the remembrance of Allah is the greatest. And Allah knoweth that which ye perform. 45 ۞ Do not argue with the people of the Book unless in a fair way, apart from those who act wrongly, and say to them: "We believe what has been sent down to us, and we believe what has been sent down to you. Our God and your God is one, and to Him we submit." 46 (O Prophet), thus have We bestowed the Book on you. So those on whom We had bestowed the Book before believe in it, and of these (Arabs) too a good many believe in it. It is none but the utter unbelievers who deny Our Signs. 47 You were not able to read any book before this, nor did you write one down with your hand. If you had done so, the followers of falsehood would have had cause to doubt it. 48 Aye! it in itself manifest signs in the breasts of those who have been vouchsafed knowledge, and none gainsay Our signs save the wrong-doers. 49 And they say: "Why are not signs sent down to him from his Lord? Say: "The signs are only with Allah, and I am only a plain warner." 50 And is it not sufficient for them that We revealed to you the Book which is recited to them? Indeed in that is a mercy and reminder for a people who believe. 51
