Recite that which has been revealed to you of the Book and keep up prayer; surely prayer keeps (one) away from indecency and evil, and certainly the remembrance of Allah is the greatest, and Allah knows what you do. 45 ۞ And dispute not with the people of the Book unless in the best manner, save with those of them who do wrong; and say: we believe in that which hath been sent down unto us and that which hath been sent down unto you: our God and your God is One; and unto Him we are submissive. 46 Likewise We have sent down the Book to you. Those to whom We gave the scripture believe in it, and so do some of your own people. Only those who deny the truth reject Our revelations. 47 (O Prophet), you did not recite any Book before, nor did you write it down with your hand; for then the votaries of falsehood would have had a cause for doubt. 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 And they said, “Why did not signs come down to him from his Lord?” Say, “Signs are only with Allah; and I am purely a Herald of plain warning.” 50 Is it not enough for them that We have sent down the Book upon you, which is read to them? Indeed in it are mercy and advice for the Muslims. 51
