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 (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 Never before did you recite any Book, or inscribe it with your right hand. If you had done so, those who follow falsehood would have doubted. 48 Rather, the Qur'an is distinct verses [preserved] within the breasts of those who have been given knowledge. And none reject Our verses except the wrongdoers. 49 They say, 'Why have signs not been gent down upon him from his Lord?' Say: 'The signs are only with God, and I am only a plain warner. 50 Is it not enough for them that We have sent down to you the Book that is recited to them? Surely, in this there is a mercy and a reminder to a nation who believe. 51
