I do not need to swear by what you see 38 as well as all that you cannot see! 39 that this is the speech of an honourable Messenger, 40 And it is not the speech of a poet; how little do you believe! 41 Nor is it the word of a soothsayer (or a foreteller), little is that you remember! 42 It has been sent down by the Lord of all 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 Then cut off his aorta, 46 not one of you could have prevented it from him. 47 It is really a reminder for those who fear God and follow the straight path. 48 And behold, well do We know that among you are such as will give the lie to it: 49 And indeed it (this Quran) will be an anguish for the disbelievers (on the Day of Resurrection). 50 And verily it is the truth of assured certainty. 51 So glorify the name of thy Tremendous Lord. 52
