Recite what has been revealed to you of this Book, and be constant in devotion. Surely prayer keeps you away from the obscene and detestable, but the remembrance of God is greater far; and God knows what you 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 Even so We have sent down to thee the Book. Those to whom We have given the Book believe in it; and some of these believe in it; and none denies Our signs but the unbelievers. 47 Not before this didst thou recite any Book, or inscribe it with thy right hand, for then those who follow falsehood would have doubted. 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 For they say: "How Is it no signs were sent down to him from his Lord?" Say: "The signs are with God. I am only a warner, plain and simple." 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
