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 argue not with the People of the Scripture unless it be in (a way) that is better, save with such of them as do wrong; and say: We believe in that which hath been revealed unto us and revealed unto you; our Allah and your Allah is One, and unto Him we surrender. 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 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 Nay, here are Signs self-evident in the hearts of those endowed with knowledge: and none but the unjust reject 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 Does it not suffice for them (as a Sign) that We revealed to you the Book that is recited to them? Surely there is mercy and good counsel in it for those who believe. 51
