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 O Muslims, do not argue with the People given the Book(s) except in the best manner – except (with) those among them who oppress, and say, “We believe in what has been sent down towards us and what has been sent towards you – and ours and your God is One, and we have submitted ourselves to Him.” 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 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 Nay! these are clear communications in the breasts of those who are granted knowledge; and none deny Our communications except the unjust. 49 But they say, "Why are not signs sent down to him from his Lord?" Say, "The signs are only with Allah, and I am only 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
