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 ۞ Do not argue with the people of the Book unless in a fair way, apart from those who act wrongly, and say to them: "We believe what has been sent down to us, and we believe what has been sent down to you. Our God and your God is one, and to Him we submit." 46 That is how We have revealed this Book to you and those to whom We have sent down the Book will believe in it. Only those who are infidels will deny it. 47 And you did not recite before it any scripture, nor did you inscribe one with your right hand. Otherwise the falsifiers would have had [cause for] doubt. 48 But the Quran is a revelation that is clear to the hearts of those endowed with knowledge. Only the evil-doers refuse to acknowledge Our revelations. 49 They ask: 'Why has not a sign been sent down upon him from his Lord' Say: 'The signs are only with Allah. I am only a clear warner' 50 Is it not enough for them that We have sent down unto thee the Scripture which is read unto them? Lo! herein verily is mercy, and a reminder for folk who believe. 51
