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 ۞ 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 (O Prophet), you did not recite any Book before, nor did you write it down with your hand; for then the votaries of falsehood would have had a cause for doubt. 48 In fact they are clear verses in the hearts of those who have been given knowledge; and none deny Our verses except the unjust. 49 They say: “Why were Signs from his Lord not sent down upon him?” Say: “The Signs are only with Allah. As for me, I am no more than 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
