But nay, I swear by all that you can see 38 and all that you do not see, 39 That it is indeed the speech of an illustrious messenger. 40 It is not the word of a poet, little is that you believe! 41 Nor is it the speech of a soothsayer; how little do you ponder! 42 It has been sent down by the Lord of all the worlds. 43 And if Muhammad had made up about Us some [false] sayings, 44 We would have seized him by the right hand, 45 Then would have cut off his heart’s artery. 46 And none of you could withhold Us from (punishing) him. 47 And indeed, the Qur'an is a reminder for the righteous. 48 And behold, well do We know that among you are such as will give the lie to it: 49 it will be a source of bitter regret for those who deny the truth -- 50 And indeed it is a certain Truth. 51 So glorify the name of thy Tremendous Lord. 52
