I swear by all that you can see, 38 And what you do not see, 39 because the Quran is certainly the word of a reverent messenger. 40 It is not the speech of a poet (little do you believe) 41 and neither is it - however little you may [be prepared to] take it to heart - the word of a soothsayer: 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 and then severed his life vein; 46 None of you would be able to prevent Us from doing this to him. 47 The Quran is certainly a reminder for the pious ones. 48 We know very well that there are some among you who reject Our signs -- 49 And most surely it is a great grief to the unbelievers. 50 And He, He is indeed the ultimate Reality. 51 So glorify the Name of your Lord, the Most Great. 52
