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 For it is thus that We have bestowed this divine writ from on high upon thee [O Muhammad]. And they to whom we have vouchsafed this divine writ believe in it just as among those [followers of earlier revelation] there are some who believe in it. And none could knowingly reject Our messages unless it be such as would deny [an obvious] truth: 47 for, [O Muhammad,] thou hast never been able to recite any divine writ ere this one [was revealed,] nor didst thou ever transcribe one with your own hand or else, they who try to disprove the truth [of thy revelation] might indeed have had cause to doubt [it]. 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 And they say: Why are not signs sent down upon him from his Lord? Say: The signs are only with Allah, and I am only a plain warner. 50 Is it not enough for them that We have sent down the Book upon you, which is read to them? Indeed in it are mercy and advice for the Muslims. 51
