But nay! I swear by all that ye see 38 and by that you do not see, 39 because the Quran is certainly the word of a reverent messenger. 40 It is not poet's speech - little is it that ye 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 Had Muhammad invented some words against Us. 44 We would have definitely taken revenge from him. 45 then, We would surely have cut from him the aorta (vein) 46 And not one of you could have withheld Us from him. 47 And most surely it is a reminder for those who guard (against evil). 48 And behold, well do We know that among you are such as will give the lie to it: 49 Surely it is a sorrow to the unbelievers; 50 Certainly it is a Truth of absolute certainty. 51 Exalt the Name of your Lord, the Great. 52
