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 argue not with the people of the Scripture (Jews and Christians), unless it be in (a way) that is better (with good words and in good manner, inviting them to Islamic Monotheism with His Verses), except with such of them as do wrong, and say (to them): "We believe in that which has been revealed to us and revealed to you; our Ilah (God) and your Ilah (God) is One (i.e. Allah), and to Him we have submitted (as Muslims)." 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 (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 But it is clear revelations in the hearts of those who have been given knowledge, and none deny Our revelations save wrong-doers. 49 They say: “Why were Signs from his Lord not sent down upon him?” Say: “The Signs are only with Allah. As for me, I am no more than a plain warner.” 50 Does it not suffice for them (as a Sign) that We revealed to you the Book that is recited to them? Surely there is mercy and good counsel in it for those who believe. 51
