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 Do they have some Gods who protect them from Us? Neither can they save themselves nor save their friends from Us. 43 Aye! We let these people and their fathers enjoy until there grew long upon them the life. Behold they not that We come unto the land diminishing it by the borders thereof? Shall they then be the victors? 44 Say: I warn you only by revelation; and the deaf do not hear the call whenever 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 shall set balances of justice for the Day of Judgment; then no soul shall be wronged at all; and if it be but the weight of a grain of mustard-seed We shall bring it; and We suffice as Reckoners. 47 We gave Moses and Aaron the Criterion, and gave them a light and a Remembrance for the cautious: 48 Who fear their Lord unseen, while they are of the Hour apprehensive. 49 This is a blessed Reminder that we have revealed: Will ye then reject it? 50
