So, I call to witness what you see 38 and by 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 And it is not the word of a poet; little do you believe. 41 Nor the word of a soothsayer; little is it that you mind. 42 It is a Revelation from the Lord of the worlds. 43 And if he had invented false sayings concerning Us, 44 We surely had lain hold of him by the right hand. 45 then, We would surely have cut from him the aorta (vein) 46 not one of you could have prevented it from him. 47 And surely it is an admonition to the God-fearing. 48 And verily, We know that there are some among you that belie (this Quran). [Tafsir At-Tabari, Vol. 29, Page 68] 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 indeed it is the truth of certainty. 51 Therefore (O dear Prophet Mohammed – peace and blessings be upon him), proclaim the purity of your Lord, the Greatest. 52
