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 ۞ 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 For it is thus that We have bestowed this divine writ from on high upon thee [O Muhammad]. And they to whom we have vouchsafed this divine writ believe in it just as among those [followers of earlier revelation] there are some who believe in it. And none could knowingly reject Our messages unless it be such as would deny [an obvious] truth: 47 And you did not recite before it any book, nor did you transcribe one with your right hand, for then could those who say untrue things have doubted. 48 Nay; rather it is signs, clear signs in the breasts of those who have been given knowledge; and none denies Our signs but the evildoers. 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 Does it not suffice for them (as a Sign) that We revealed to you the Book that is recited to them? Surely there is mercy and good counsel in it for those who believe. 51
