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 And thus have We revealed the Book to you. So those whom We have given the Book believe in it, and of these there are those who believe in it, and none deny Our communications except the unbelievers. 47 Not before this didst thou recite any Book, or inscribe it with thy right hand, for then those who follow falsehood would 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 And they say: wherefore are not signs sent down upon him from his Lord! Say thou: signs are with Allah only, and I am but a manifest warner. 50 And is it not enough for them that we have sent down to thee the Book which is rehearsed to them? Verily, in it is Mercy and a Reminder to those who believe. 51
