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 do not dispute with the followers of the Book except by what is best, except those of them who act unjustly, and say: We believe in that which has been revealed to us and revealed to you, and our Allah and your Allah is One, and to Him do we submit. 46 And thus We have sent down to you the Qur'an. And those to whom We [previously] gave the Scripture believe in it. And among these [people of Makkah] are those who believe in it. And none reject Our verses except the disbelievers. 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 they are clear verses in the hearts of those who have been given knowledge; and none deny Our verses except the 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 to you the Book which is recited to them? Most surely there is mercy in this and a reminder for a people who believe. 51
