I swear by that which ye see. 38 And that which ye see not. 39 That this is indeed the word of the noble Messenger, 40 It is not the word of a poet: little it is ye believe! 41 Nor is this the speech of a soothsayer. Little do you reflect! 42 It is a revelation from the Lord of the Universe. 43 And if he [i.e., the Prophets] had forged this Discourse and thereafter ascribed it to Us, 44 We would have definitely taken revenge from him. 45 and would indeed have cut his life-vein, 46 None of you would be able to prevent Us from doing this to him. 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 for, verily, it is truth absolute! 51 Wherefore hallow thou the name of thy Lord, the Mighty. 52
