BUT NAY! I call to witness all that you can see, 38 and by that you do not see, 39 most surely, this is the word brought by a noble messenger, 40 It is not poet's speech - little is it that ye believe! 41 Nor is it the word of a soothsayer (or a foreteller), little is that you remember! 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 Then We would have cut from him the aorta. 46 And not one of you could have held Us off from him. 47 And verily, this [Qur'an] is a reminder to all the God-conscious! 48 And We certainly know that there are amongst you those that reject (it). 49 And indeed it (this Quran) will be an anguish for the disbelievers (on the Day of Resurrection). 50 yet it is a certain truth. 51 So glorify the Name of your Lord, the Most Great. 52
