But no; I swear by what you see, 38 and what you do not see 39 that this is the speech of an honourable Messenger, 40 And it is not the speech of a poet. Little it is that ye believe 41 Nor diviner's speech - little is it that ye remember! 42 [it is] a revelation from the Sustainer 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 caught hold of him by his right hand 45 and then severed his life vein; 46 And not one of you would have been able to stop (Us). 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 yet, behold, this [rejection] will indeed become a source of bitter regret for all who deny the truth [of God's revelation] 50 But verily it is Truth of assured certainty. 51 (Muhammad), glorify the name of your Lord, the Great One. 52
