Recite thou that which hath been revealed unto thee of the Book and establish thou the prayer; verily prayer preventeth man from indecency and that which is disreputable: and surely the remembrance of Allah is the greatest. And Allah knoweth that which ye perform. 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 As such, We have sent down to you the Book. Those to whom We gave the Book believe in it, and so do some of these. None reject Our verses except the unbelievers. 47 You were not able to read any book before this, nor did you write one down with your hand. If you had done so, the followers of falsehood would have had cause to doubt it. 48 Nay, here are Signs self-evident in the hearts of those endowed with knowledge: and none but the unjust reject Our Signs. 49 They say, "Why has no sign been given to him by his Lord?" Say, "The signs are in the hands of God. I am but a plain 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
