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 ۞ Believers, argue only in the best way with the People of the Book, [but contend not at all] with such of them as are unjust. Say, "We believe in what has been revealed to us, and what has been revealed to you; our God and your God are one; and to Him we submit." 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 Never before did you recite any Book, or inscribe it with your right hand. If you had done so, those who follow falsehood would have doubted. 48 Rather, the Qur'an is distinct verses [preserved] within the breasts of those who have been given knowledge. And none reject Our verses except the wrongdoers. 49 They say, 'Why have signs not been gent down upon him from his Lord?' Say: 'The signs are only with God, 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
