I do not need to swear by what you see 38 and what you do not see 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 It is not the word of a poet, little is that you believe! 41 Nor is this the speech of a soothsayer. Little do you reflect! 42 [it is] a revelation from the Sustainer of all the worlds. 43 Had he invented against Us any sayings, 44 We would have seized him by the right hand, 45 then, We would surely have cut from him the aorta (vein) 46 And not one of you would have been able to stop (Us). 47 But verily this is a Message for the Allah-fearing. 48 And verily, We know that there are some among you that belie (this Quran). [Tafsir At-Tabari, Vol. 29, Page 68] 49 And indeed it (this Quran) will be an anguish for the disbelievers (on the Day of Resurrection). 50 And most surely it is the true certainty 51 Exalt the Name of your Lord, the Great. 52
