I do not need to swear by what you see 38 And what ye see not, 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 It is a revelation sent down by the Sustainer 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 cut-off his main artery. 46 not one of you could have prevented it from him. 47 And surely it is an admonition to the God-fearing. 48 We know very well that there are some among you who reject Our signs -- 49 And verily it shall be an occasion of anguish unto the infidels. 50 And most surely it is the true certainty 51 (Muhammad), glorify the name of your Lord, the Great One. 52
