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 ۞ Believers, argue only in the best way with the People of the Book, [but contend not at all] with such of them as are unjust. Say, "We believe in what has been revealed to us, and what has been revealed to you; our God and your God are one; and to Him we submit." 46 In like manner We have revealed unto thee the Scripture, and those unto whom We gave the Scripture aforetime will believe therein; and of these (also) there are some who believe therein. And none deny Our revelations save 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 But it is a set of Clear Signs in the hearts of those who have been endowed with knowledge. None except the utterly unjust will deny Our Signs. 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 to you the Book that is recited to them? Surely, in this there is a mercy and a reminder to a nation who believe. 51
