But nay! I swear by that which you see, 38 as well as all that you cannot see! 39 that this is the speech of a noble Messenger. 40 And it is not the speech of a poet; how little do you believe! 41 Nor is it the speech of a sooth-sayer. Little are ye admonished. 42 It is a revelation from the Lord of the worlds. 43 And if he [i.e., the Prophets] had forged this Discourse and thereafter ascribed it to Us, 44 We surely had lain hold of him by the right hand. 45 then, We would surely have cut from him the aorta (vein) 46 And not one of you could have held Us off from him. 47 And surely it is an admonition to the God-fearing. 48 but We know that some of you will cry lies. 49 and (on the Day of Judgment) this will be a great source of regret for the unbelievers. 50 And Verily, it (this Quran) is an absolute truth with certainty. 51 So exalt the name of your Lord, the Most Great. 52
