Say, "Who can protect you at night or by day from the Most Merciful?" But they are, from the remembrance of their Lord, turning away. 42 Or have they gods to defend them, other than Us? Indeed, they are unable to help themselves, neither shall they be guarded in safety 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 thy Lord's punishment were to touch them, they assuredly would say: Alas for us! Lo! we were wrong-doers. 46 And We set a just balance for the Day of Resurrection so that no soul is wronged in aught. Though it be of the weight of a grain of mustard seed, We bring it. And We suffice for reckoners. 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
