(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 (O Prophet), thus have We bestowed the Book on you. So those on whom We had bestowed the Book before believe in it, and of these (Arabs) too a good many believe in it. It is none but the utter unbelievers who deny Our Signs. 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 But it is a set of Clear Signs in the hearts of those who have been endowed with knowledge. None except the utterly unjust will deny Our Signs. 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 the Book upon you, which is read to them? Indeed in it are mercy and advice for the Muslims. 51
