But nay! I swear by that which you see, 38 as well as all that you cannot see: 39 That it is surely the speech brought by messenger honourable. 40 and is not - however little you may [be prepared to] believe it - the word of a poet; 41 nor is it the work of a soothsayer but only a few of you take heed. 42 It is a revelation sent down by the Sustainer of the Universe: 43 And if he [i.e., the Prophets] had forged this Discourse and thereafter ascribed it to 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 would have been able to stop (Us). 47 And lo! it is a warrant unto those who ward off (evil). 48 And verily We! We know that some among you are beliers thereof. 49 and surely it will be a cause of regret for the unbelievers. 50 But verily it is Truth of assured certainty. 51 So exalt the name of your Lord, the Most Great. 52
