I swear by that which ye see. 38 and by what you do not see, 39 [That] indeed, the Qur'an is the word of a noble Messenger. 40 it is not the word of a poet -- how little you believe! -- 41 Nor the word of a soothsayer; little do you remember. 42 It is a revelation sent down by the Sustainer of the Universe: 43 And if Muhammad had made up about Us some [false] sayings, 44 We would have definitely taken revenge from him. 45 And then severed his life-vein. 46 And not one of you could have held Us off from him. 47 And verily, this Quran is a Reminder for the Muttaqun (pious - see V. 2:2). 48 And most surely We know that some of you are rejecters. 49 and (on the Day of Judgment) this will be a great source of regret for the unbelievers. 50 yet it is a certain truth. 51 Therefore (O dear Prophet Mohammed – peace and blessings be upon him), proclaim the purity of your Lord, the Greatest. 52
