Say: 'Who shall guard you by night and in the daytime from the All-merciful?' Nay, but from the Remembrance of their Lord they are turning away. 42 Or have they gods that can guard them from Us? They have no power to aid themselves, nor can they be defended from Us. 43 Nay, We gave the luxuries of this life to these men and their fathers until the period grew long for them. See they not that We gradually reduce the land (in their control) from its outlying borders? Is it then they who will overcome. 44 Say: 'I warn you only by the Revelation' But the deaf hear nothing when they are warned. 45 And if a breath of thy Lord's punishment were to touch them, they assuredly would say: Alas for us! Lo! we were 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 AND, INDEED, We vouchsafed unto Moses and Aaron [Our revelation as] the standard by which to discern the true from the false, and as a [guiding] light and a reminder for the God-conscious 48 Who fear their Lord unseen, while they are of the Hour apprehensive. 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
