Recite what has been revealed to you of this Book, and be constant in devotion. Surely prayer keeps you away from the obscene and detestable, but the remembrance of God is greater far; and God knows what you do. 45 ۞ And dispute not with the people of the Book unless in the best manner, save with those of them who do wrong; and say: we believe in that which hath been sent down unto us and that which hath been sent down unto you: our God and your God is One; and unto Him we are submissive. 46 In like manner We have revealed unto thee the Scripture, and those unto whom We gave the Scripture aforetime will believe therein; and of these (also) there are some who believe therein. And none deny Our revelations save the disbelievers. 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 signs sent down to him from his Lord? Say: "The signs are only with Allah, and I am only a plain warner." 50 Is it not sufficient for them that We have revealed the Book to you which is read out to them? It is indeed a grace and reminder for people who believe. 51
