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 (O Prophet), thus have We bestowed the Book on you. So those on whom We had bestowed the Book before believe in it, and of these (Arabs) too a good many believe in it. It is none but the utter unbelievers who deny Our Signs. 47 for, [O Muhammad,] thou hast never been able to recite any divine writ ere this one [was revealed,] nor didst thou ever transcribe one with your own hand or else, they who try to disprove the truth [of thy revelation] might indeed have had cause to doubt [it]. 48 Nay; rather it is signs, clear signs in the breasts of those who have been given knowledge; and none denies Our signs but the evildoers. 49 And they say: "Why are not signs sent down to him from his Lord? Say: "The signs are only with Allah, and I am only a plain warner." 50 What, is it not sufficient for them that We have sent down upon thee the Book that is recited to them? Surely in that is a mercy, and a reminder to a people who believe. 51
