I swear by that which ye see. 38 and by that 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 poet's speech - little is it that ye believe! 41 Nor the word of a soothsayer; little is it that you mind. 42 It is a revelation from the Lord of the Universe. 43 Had he attributed falsely any words to Us, 44 We would have definitely taken revenge from him. 45 then We would surely have cut his life-vein 46 And not one of you could have withheld Us from him. 47 And most surely it is a reminder for those who guard (against evil). 48 And verily, We know that there are some among you that belie (this Quran). [Tafsir At-Tabari, Vol. 29, Page 68] 49 And most surely it is a great grief to the unbelievers. 50 for, verily, it is truth absolute! 51 Therefore (O dear Prophet Mohammed – peace and blessings be upon him), proclaim the purity of your Lord, the Greatest. 52
