I do not need to swear by what you see 38 And by whatsoever you see not, 39 That this is verily the word of an honoured Messenger [i.e. Jibrael (Gabriel) or Muhammad SAW which he has brought from Allah]. 40 And not the word of a poet. How little is it that you believe! 41 and neither is it - however little you may [be prepared to] take it to heart - the word of a soothsayer: 42 [it is] a revelation from the Sustainer 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 And then certainly should have cut off his life artery (Aorta), 46 and none of you could have held Us off from him. 47 The Quran is certainly a reminder for the pious ones. 48 And behold, well do We know that among you are such as will give the lie to 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 And indeed, it is the truth of certainty. 51 Extol, then the limitless glory of thy Sustainer's mighty name! 52
