But no; I swear by what you see, 38 And by whatsoever you see not, 39 [That] indeed, the Qur'an is the word of a noble Messenger. 40 And it is not the word of a poet; little is it that you believe; 41 Nor is this the speech of a soothsayer. Little do you reflect! 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 And We should certainly then cut off the artery of his heart: 46 and not one of you would have been able to withhold Us from doing so. 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 But truly (Revelation) is a cause of sorrow for the Unbelievers. 50 Certainly it is a Truth of absolute certainty. 51 So glorify the name of your Lord, the Almighty. 52
