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 argue with the followers of earlier revelation otherwise than in a most kindly manner - unless it be such of them as are bent on evildoing and say: "We believe in that which has been bestowed from on high upon us, as well as that which has been bestowed upon you: or our God and your God is one and the same, and it is unto Him that We [all] surrender ourselves." 46 In like manner We have revealed unto thee the Scripture, and those unto whom We gave the Scripture aforetime will believe therein; and of these (also) there are some who believe therein. And none deny Our revelations save the disbelievers. 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 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 Is it not enough for them that We have revealed to you the Book which is recited to them? Most surely there is mercy in this and a reminder for a people who believe. 51
