Recite what is sent of the Book by inspiration to thee, and establish regular Prayer: for Prayer restrains from shameful and unjust deeds; and remembrance of Allah is the greatest (thing in life) without doubt. And Allah knows the (deeds) that ye do. 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 or write before the Quran was revealed to you; otherwise, the followers of falsehood would have tried to confuse the matter. 48 In fact, in the minds of those who have intelligence these are clear signs. No one denies Our revelations except those who are unjust. 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 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
