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 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 And thus have We revealed the Book to you. So those whom We have given the Book believe in it, and of these there are those who believe in it, and none deny Our communications except the unbelievers. 47 And thou wast not (able) to recite a Book before this (Book came), nor art thou (able) to transcribe it with thy right hand: In that case, indeed, would the talkers of vanities have doubted. 48 But it is a set of Clear Signs in the hearts of those who have been endowed with knowledge. None except the utterly unjust will deny Our Signs. 49 And they say: Why are not portents sent down upon him from his Lord? Say: Portents are with Allah only, and I am but a plain warner. 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
