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 Rather, the Qur'an is distinct verses [preserved] within the breasts of those who have been given knowledge. And none reject Our verses except the wrongdoers. 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 Why - is it not enough for them that We have bestowed this divine writ on thee from on high, to be conveyed [by thee] to them? For, verily, in it is [manifested Our] grace, and a reminder to people who will believe. 51
