(Muhammad), recite to them what has been revealed to you in the Book and be steadfast in prayer; prayer keeps one away from indecency and evil. It is the greatest act of worshipping God. God knows what you 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 And thus have We revealed the Book to you. So those whom We have given the Book believe in it, and of these there are those who believe in it, and none deny Our communications except the unbelievers. 47 for, [O Muhammad,] thou hast never been able to recite any divine writ ere this one [was revealed,] nor didst thou ever transcribe one with your own hand or else, they who try to disprove the truth [of thy revelation] might indeed have had cause to doubt [it]. 48 In fact they are clear verses in the hearts of those who have been given knowledge; and none deny Our verses except the unjust. 49 They say, 'Why have signs not been gent down upon him from his Lord?' Say: 'The signs are only with God, and I am only a plain warner. 50 And is it not enough for them that we have sent down to thee the Book which is rehearsed to them? Verily, in it is Mercy and a Reminder to those who believe. 51
