Recite thou that which hath been revealed unto thee of the Book and establish thou the prayer; verily prayer preventeth man from indecency and that which is disreputable: and surely the remembrance of Allah is the greatest. And Allah knoweth that which ye perform. 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 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 (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 No, rather they are clear verses in the chests of those who have been given knowledge. None disbelieves Our verses except the harmdoers. 49 But they say, "Why are not signs sent down to him from his Lord?" Say, "The signs are only with Allah, and I am only a clear warner." 50 Is it not sufficient for them that We have sent you down the Book to be recited to them? In this surely there is a blessing and an admonition for a people who believe. 51
