Say: 'Who will guard you, by night and by day from the Merciful' But no, they turn away from their Lord's remembrance. 42 Do they have other deities who can defend them against Us? They cannot even help themselves, neither can they be aided against Us. 43 Nay, We gave the good things 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 win? 44 Say, "I only warn you by revelation." But the deaf do not hear the call when they are warned. 45 Were only the slightest whiff from your Lord's punishment to touch them, they would cry out: "Woe to us; we were indeed wrong-doers." 46 And We place the scales of justice for the Day of Resurrection, so no soul will be treated unjustly at all. And if there is [even] the weight of a mustard seed, We will bring it forth. And sufficient are We as accountant. 47 We gave Moses and Aaron the criterion of right and wrong and a light and reminder for the righteous, 48 Who fear their Lord unseen, while they are of the Hour apprehensive. 49 And this is a blessed Message which We have sent down: will ye then reject it? 50
