Recite that which has been revealed to you of the Book and keep up prayer; surely prayer keeps (one) away from indecency and evil, and certainly the remembrance of Allah is the greatest, and Allah 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 for, [O Muhammad,] thou hast never been able to recite any divine writ ere this one [was revealed,] nor didst thou ever transcribe one with your own hand or else, they who try to disprove the truth [of thy revelation] might indeed have had cause to doubt [it]. 48 No, rather they are clear verses in the chests of those who have been given knowledge. None disbelieves Our verses except the harmdoers. 49 And they say: Why are not signs sent down upon him from his Lord? Say: The signs are only with Allah, and I am only a plain warner. 50 Is it not sufficient for them that We have sent down to you the Book (the Quran) which is recited to them? Verily, herein is mercy and a reminder (or an admonition) for a people who believe. 51
