No! I swear by that you see 38 And what you do not see, 39 that this is the speech of a noble Messenger. 40 It is not the word of a poet: little it is ye believe! 41 Nor is it the speech of a soothsayer; how little do you ponder! 42 It is a Revelation from the Lord of the worlds. 43 Had he attributed falsely any words to Us, 44 We would have definitely taken revenge from him. 45 And then severed his life-artery, 46 not one of you could have prevented it from him. 47 And most surely it is a reminder for those who guard (against evil). 48 but We know that some of you will cry lies. 49 And indeed it (this Quran) will be an anguish for the disbelievers (on the Day of Resurrection). 50 And indeed, it is the truth of certainty. 51 Therefore (O dear Prophet Mohammed – peace and blessings be upon him), proclaim the purity of your Lord, the Greatest. 52
