I do not need to swear by what you see 38 And by oath of those you do not see. 39 That it is indeed the speech of an illustrious messenger. 40 It is not the speech of a poet (little do you believe) 41 Nor diviner's speech - little is it that ye remember! 42 (This is) a Message sent down from the Lord of the Worlds. 43 And if Muhammad had made up about Us some [false] sayings, 44 We would have seized him by the right hand, 45 And We should certainly then cut off the artery of his heart: 46 And not one of you would have been able to stop (Us). 47 Surely it is a Good Counsel for the God-fearing. 48 And verily We! We know that some among you are beliers thereof. 49 And most surely it is a great grief to the unbelievers. 50 Certainly it is a Truth of absolute certainty. 51 Therefore (O dear Prophet Mohammed – peace and blessings be upon him), proclaim the purity of your Lord, the Greatest. 52
