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 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 you did not recite before it any book, nor did you transcribe one with your right hand, for then could those who say untrue things 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 For they say: "How Is it no signs were sent down to him from his Lord?" Say: "The signs are with God. I am only a warner, plain and simple." 50 Sufficeth it not for them that We have sent down unto thee the Book to be recited unto them? Verily herein is a mercy and an admonition for a people who believe. 51
