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 ۞ 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 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 thou hast not been reciting any book before it, nor hast thou been writing it with thine right hand, for then might the followers of falsehood have doubted. 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 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 enough for them that We have revealed the Book to you to be recited to them. It is a mercy and a reminder for the believers. 51
