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 do not dispute with the People of the Book (Nazarenes) except in the best manner, except for those among them who do wrong and say (to them): 'We believe in that which was sent down to us and that which was sent down to you. Our God and your God is One, and to Him we have surrendered' 46 Even so We have sent down to thee the Book. Those to whom We have given the Book believe in it; and some of these believe in it; and none denies Our signs but the unbelievers. 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 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 And they said, “Why did not signs come down to him from his Lord?” Say, “Signs are only with Allah; and I am purely a Herald of plain warning.” 50 Is it not enough for them that We have revealed to you the Book which is recited to them? Most surely there is mercy in this and a reminder for a people who believe. 51
