CONVEY [unto others] whatever of this divine writ has been revealed unto thee, and be constant in prayer: for, behold, prayer restrains [man] from loathsome deeds and from all that runs counter to reason; and remembrance of God is indeed the greatest [good]. And God knows all that 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 Neither did you (O Muhammad SAW) read any book before it (this Quran), nor did you write any book (whatsoever) with your right hand. In that case, indeed, the followers of falsehood might have doubted. 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 Ye they say: "Why are not Signs sent down to him from his Lord?" Say: "The signs are indeed with Allah: and I am indeed a clear 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
