But no; I swear by what you see, 38 And what you do not see 39 that this is the speech of a noble Messenger. 40 it is not the word of a poet -- how little you believe! -- 41 Nor the word of a soothsayer; little do you remember. 42 It has been sent down by the Lord of all the worlds. 43 And if the messenger were to invent any sayings in Our name, 44 We assuredly had taken him by the right hand 45 Then cut off his aorta, 46 And none of you could withhold Us from (punishing) him. 47 Indeed, it is a Reminder to those who fear Allah, 48 We know very well that there are some among you who reject Our signs -- 49 And indeed it (this Quran) will be an anguish for the disbelievers (on the Day of Resurrection). 50 Certainly it is a Truth of absolute certainty. 51 (Muhammad), glorify the name of your Lord, the Great One. 52
