Say: "Who guards you from Ar-Rahman by night and by day?" Yet from a mention of their Lord they turn away. 42 Or, have they gods who can defend them against Us? They shall not be able to assist themselves, nor shall they be defended from Us. 43 Nay, We generously provided them and their fathers, and they enjoyed Our provision for long. Do they not see that We are now advancing into their territory, diminishing it from different sides? Is it they, then, who will triumph?" 44 Say: 'I warn you only by the Revelation'; but they that are deaf do not hear the call when they are warned. 45 And if a breath of the torment of thy Lord were to touch them, they will say: woe unto us! we have been wrong-doers. 46 We shall set up just scales on the Day of Resurrection so that none will be wronged in the least. (We shall bring forth the acts of everyone), even if it be the weight of a grain of mustard seed. We shall suffice as Reckoners. 47 And assuredly We vcuchsafed unto Musa and Harun the distinction and illumination and an admonition for the God-fearing. 48 for those who fear their Lord without seeing Him and dread the Hour (of Reckoning). 49 And this is a blessed Remembrance that We have sent down; so are you now denying it? 50
