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 Even so We have sent down to thee the Book. Those to whom We have given the Book believe in it; and some of these believe in it; and none denies Our signs but 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 But it is a set of Clear Signs in the hearts of those who have been endowed with knowledge. None except the utterly unjust will deny Our Signs. 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 What, is it not sufficient for them that We have sent down upon thee the Book that is recited to them? Surely in that is a mercy, and a reminder to a people who believe. 51
