BUT NAY! I call to witness all that you can see, 38 as well as all that you cannot see! 39 that this is the speech of a noble Messenger. 40 and is not - however little you may [be prepared to] believe it - the word of a poet; 41 Nor is it the word of a soothsayer -- how little you reflect! 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 indeed have seized him by his right hand 45 then, We would surely have cut from him the aorta (vein) 46 None of you would be able to prevent Us from doing this to him. 47 It is really a reminder for those who fear God and follow the straight path. 48 We certainly know that some among you do deny it. 49 And indeed it (this Quran) will be an anguish for the disbelievers (on the Day of Resurrection). 50 And most surely it is the true certainty 51 Therefore-glorify the name of your Lord, the Great. 52
