I swear by all that you can see, 38 and by what you do not see, 39 That this is indeed the word of the noble Messenger, 40 It is not poet's speech - little is it that ye believe! 41 and neither is it - however little you may [be prepared to] take it to heart - the word of a soothsayer: 42 It has been revealed by the Lord of the Universe. 43 And if Muhammad had made up about Us some [false] sayings, 44 We would indeed have seized him by his right hand, 45 And We should certainly then cut off the artery of his heart: 46 And not one of you could have held Us off from him. 47 And indeed, the Qur'an is a reminder for the righteous. 48 And indeed We know that some among you are deniers. 49 yet, behold, this [rejection] will indeed become a source of bitter regret for all who deny the truth [of God's revelation] 50 yet it is a certain truth. 51 Therefore (O dear Prophet Mohammed – peace and blessings be upon him), proclaim the purity of your Lord, the Greatest. 52
