I swear by all that you can see, 38 as well as all that you cannot see! 39 [That] indeed, the Qur'an is the word of a noble Messenger. 40 And it is not the word of a poet; little do you believe. 41 nor is it the work of a soothsayer but only a few of you take heed. 42 [It is] a revelation from the Lord of the worlds. 43 Now if he [whom We have entrusted with it] had dared to attribute some [of his own] sayings unto Us, 44 We would have seized him by the right hand 45 And We should certainly then cut off the artery of his heart: 46 And there is no one of you who could prevent [Us] from him. 47 Indeed, it is a Reminder to those who fear Allah, 48 We know very well that there are some among you who reject Our signs -- 49 It is surely the nemesis of unbelievers. 50 But verily it is Truth of assured certainty. 51 Therefore (O dear Prophet Mohammed – peace and blessings be upon him), proclaim the purity of your Lord, the Greatest. 52
