Recite that which hath been inspired in thee of the Scripture, and establish worship. Lo! worship preserveth from lewdness and iniquity, but verily remembrance of Allah is more important. And Allah knoweth what ye do. 45 ۞ Do not argue with the People of the Book except only by the best manner, except the unjust among them. Tell them, "We believe in what is revealed to us and to you. Our Lord and your Lord is one. We have submitted ourselves to His will". 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 And thou (O Muhammad) wast not a reader of any scripture before it, nor didst thou write it with thy right hand, for then might those have doubted, who follow falsehood. 48 But the Quran is a revelation that is clear to the hearts of those endowed with knowledge. Only the evil-doers refuse to acknowledge Our revelations. 49 And they say: Why are not portents sent down upon him from his Lord? Say: Portents are with Allah only, and I am but a plain warner. 50 What, is it not sufficient for them that We have sent down upon thee the Book that is recited to them? Surely in that is a mercy, and a reminder to a people who believe. 51
