But nay, I swear by all that you can see 38 and what you do not see 39 Behold, this [Qur'an] is indeed the [inspired] word of a noble apostle, 40 not the speech of a poet. Little do you believe! 41 Nor is it the word of a soothsayer -- how little you reflect! 42 (It is) a sending down from the Lord of all the Worlds. 43 And if he [i.e., the Prophets] had forged this Discourse and thereafter ascribed it to Us, 44 We would have seized him by his right hand, 45 Then cut off his aorta, 46 And not one of you could have held Us off from him. 47 And verily it is an admonition unto the God-fearing. 48 We certainly know that some among you will give the lie to it, 49 It is surely the nemesis of unbelievers. 50 And Verily, it (this Quran) is an absolute truth with certainty. 51 Therefore (O dear Prophet Mohammed – peace and blessings be upon him), proclaim the purity of your Lord, the Greatest. 52
