I do not need to swear by what you see 38 And by whatsoever you see not, 39 that this is the speech of a noble Messenger. 40 It is not the speech of a poet little do you believe 41 Nor is it the word of a soothsayer. Little is it that you reflect! 42 It has been sent down by the Lord of all the worlds. 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 would have cut off his heart's artery. 46 and not one of you could have defended him. 47 The Quran is certainly a reminder for the pious ones. 48 And We certainly know that there are amongst you those that reject (it). 49 yet, behold, this [rejection] will indeed become a source of bitter regret for all who deny the truth [of God's revelation] 50 yet it is a certain truth. 51 Therefore-glorify the name of your Lord, the Great. 52
