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 followers of the Book except by what is best, except those of them who act unjustly, and say: We believe in that which has been revealed to us and revealed to you, and our Allah and your Allah is One, and to Him do we submit. 46 And thus (it is) that We have sent down the Book to thee. So the People of the Book believe therein, as also do some of these (pagan Arabs): and none but Unbelievers reject our signs. 47 And thou (O Muhammad) wast not a reader of any scripture before it, nor didst thou write it with thy right hand, for then might those have doubted, who follow falsehood. 48 Rather, the Qur'an is distinct verses [preserved] within the breasts of those who have been given knowledge. And none reject Our verses except the wrongdoers. 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 revealed the Book to you to be recited to them. It is a mercy and a reminder for the believers. 51
