Say: Who guards you by night and by day from the Beneficent Allah? Nay, they turn aside at the mention of their Lord. 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 We allowed them and their fathers time to enjoy till the very end of their lives. Do they not see Us advancing into the land, reducing its frontiers? Would they still prevail? 44 Say: 'I warn you only by the Revelation' But the deaf hear nothing 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 But We shall set up just balance-scales on Resurrection Day, and no human being shall be wronged in the least: for though there be [in him but] the weight of a mustard-seed [of good or evil,] We shall bring it forth; and none can take count as We do! 47 We gave Moses and Aaron the criterion of right and wrong and a light and reminder for the righteous, 48 Those who fear their Lord in secret and who dread the Hour (of doom). 49 And [like those earlier revelations,] this one, too, is a blessed reminder which We have bestowed from on high: will you, then, disavow it? 50
