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 As such, We have sent down to you the Book. Those to whom We gave the Book believe in it, and so do some of these. None reject Our verses except the unbelievers. 47 And thou wast not (able) to recite a Book before this (Book came), nor art thou (able) to transcribe it with thy right hand: In that case, indeed, would the talkers of vanities have doubted. 48 No, rather they are clear verses in the chests of those who have been given knowledge. None disbelieves Our verses except the harmdoers. 49 They say, "Why has no sign been given to him by his Lord?" Say, "The signs are in the hands of God. I am but a plain warner." 50 Is it not enough for them that We have revealed the Book to you to be recited to them. It is a mercy and a reminder for the believers. 51
