So I do call to witness what ye see, 38 And by whatsoever you see not, 39 That it is surely the speech brought by messenger honourable. 40 And it is not the word of a poet; little do you believe. 41 Nor is it the word of a soothsayer: little admonition it is ye receive. 42 It is a revelation from the Lord of the Worlds. 43 Had Muhammad invented some words against Us. 44 We would have definitely taken revenge from him. 45 And then severed his life-vein. 46 None of you would be able to prevent Us from doing this to him. 47 It is really a reminder for those who fear God and follow the straight path. 48 And verily, We know that there are some among you that belie (this Quran). [Tafsir At-Tabari, Vol. 29, Page 68] 49 And verily it shall be an occasion of anguish unto the infidels. 50 And verily it is the truth of assured certainty. 51 So glorify your Lord, the most supreme. 52
