So, I call to witness what you see 38 as well as all that you cannot see: 39 That it is indeed the speech of an illustrious messenger. 40 it is not the word of a poet -- how little 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 then severed his life vein; 46 and none of you could have held Us off from him. 47 But verily this is a Message for the Allah-fearing. 48 We certainly know that some among you do deny it. 49 But truly (Revelation) is a cause of sorrow for the Unbelievers. 50 Certainly it is a Truth of absolute certainty. 51 So glorify the name of your Lord Most Great. 52
