So, I call to witness what you see 38 as well as all that you cannot see! 39 most surely, this is the word brought by a noble messenger, 40 It is not the word of a poet, little is that you believe! 41 Nor diviner's speech - little is it that ye remember! 42 [It is] a revelation from the Lord of the worlds. 43 Had Muhammad invented some words against Us. 44 We should certainly seize him by his right hand, 45 And We should certainly then cut off the artery of his heart: 46 Then none among you would be his saviour. 47 And indeed this Qur'an is an advice for the pious. 48 And lo! We know that some among you will deny (it). 49 and (on the Day of Judgment) this will be a great source of regret for the unbelievers. 50 it is the indubitable truth. 51 So glorify the name of your Lord, the Almighty. 52
