But nay! I swear by that which you see, 38 And by whatsoever you see not, 39 it is the speech of a noble Messenger. 40 It is not poet's speech - little is it that ye believe! 41 Nor diviner's speech - little is it that ye remember! 42 It is a revelation sent down by the Sustainer of the Universe: 43 Had Muhammad invented some words against Us. 44 We would have seized him by the 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 We certainly know that there are amongst you those that reject (it). 49 Surely it is a sorrow to the unbelievers; 50 Certainly it is a Truth of absolute certainty. 51 Therefore (O dear Prophet Mohammed – peace and blessings be upon him), proclaim the purity of your Lord, the Greatest. 52
