So I do call to witness what ye see, 38 as well as all that you cannot see! 39 That it is indeed the speech of an illustrious messenger. 40 not the speech of a poet. Little do you believe! 41 and neither is it - however little you may [be prepared to] take it to heart - the word of a soothsayer: 42 It is a revelation from the Lord of the Worlds. 43 Had Muhammad invented some words against Us. 44 We would have caught hold of him by his right hand 45 and then severed his life vein; 46 and not one of you would have been able to withhold Us from doing so. 47 And verily, this [Qur'an] is a reminder to all the God-conscious! 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 But verily it is Truth of assured certainty. 51 Exalt the Name of your Lord, the Great. 52
