Say: "Who guards you from Ar-Rahman by night and by day?" Yet from a mention of their Lord they turn away. 42 Or do they have lords of their own besides Us who can defend them? But they are not able to help themselves, nor can they find protection against Us. 43 Nay, We have allowed these [sinners] - as [We allowed] their forebears - to enjoy the good things of life for a great length of time: but then - have they never yet seen how We visit the earth [with Our punishment,] gradually depriving it of all that is best thereon? Can they, then, [hope to] be the winners? 44 Say thou: I only warn you by the revelation; and the deaf hearken not unto the call when they are warned. 45 But if just a breath of your Lord's punishment were to touch them, they would say: 'Woe for us, we were harmdoers' 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, and a light and reminder for those who take heed for themselves, 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
