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 (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 You were not able to read any book before this, nor did you write one down with your hand. If you had done so, the followers of falsehood would have had cause to doubt it. 48 Nay, here are Signs self-evident in the hearts of those endowed with knowledge: and none but the unjust reject Our Signs. 49 And they say: Why are not portents sent down upon him from his Lord? Say: Portents are with Allah only, and I am but a plain warner. 50 Is it not sufficient for them that We have revealed the Book to you which is read out to them? It is indeed a grace and reminder for people who believe. 51
