Recite what is sent of the Book by inspiration to thee, and establish regular Prayer: for Prayer restrains from shameful and unjust deeds; and remembrance of Allah is the greatest (thing in life) without doubt. And Allah knows the (deeds) that ye 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 (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 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, but this [divine writ] consists of messages clear to the hearts of all who are gifted with [innate] knowledge and none could knowingly reject Our messages unless it be such as would do wrong [to themselves]. 49 Ye they say: "Why are not Signs sent down to him from his Lord?" Say: "The signs are indeed with Allah: and I am indeed a clear 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
