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 (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 In fact, the Quran consists of illustrious verses that exist in the hearts of those who have knowledge. No one rejects Our revelations except the unjust ones. 49 And they say: wherefore are not signs sent down upon him from his Lord! Say thou: signs are with Allah only, and I am but a manifest warner. 50 Is it not enough for them that We have sent down unto thee the Scripture which is read unto them? Lo! herein verily is mercy, and a reminder for folk who believe. 51
