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 ۞ And argue not with the people of the Scripture (Jews and Christians), unless it be in (a way) that is better (with good words and in good manner, inviting them to Islamic Monotheism with His Verses), except with such of them as do wrong, and say (to them): "We believe in that which has been revealed to us and revealed to you; our Ilah (God) and your Ilah (God) is One (i.e. Allah), and to Him we have submitted (as Muslims)." 46 That is how We have revealed this Book to you and those to whom We have sent down the Book will believe in it. Only those who are infidels will deny it. 47 And thou (O Muhammad) wast not a reader of any scripture before it, nor didst thou write it with thy right hand, for then might those have doubted, who follow falsehood. 48 But the Quran is a revelation that is clear to the hearts of those endowed with knowledge. Only the evil-doers refuse to acknowledge Our revelations. 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 unto thee the Scripture which is read unto them? Lo! herein verily is mercy, and a reminder for folk who believe. 51
