Say: "Who guards you from Ar-Rahman by night and by day?" Yet from a mention of their Lord they turn away. 42 Do they [really think that they] have deities that could shield them from Us? Those [alleged deities] are not [even] able to succour themselves: hence, neither can they [who worship them hope to] be aided [by them] against 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 do but warn you according to revelation": But the deaf will not hear the call, (even) when they are warned! 45 Even if a whiff of the Lord's chastisement were to touch them they would surely say: "Ah woe, alas, we were surely sinful." 46 We shall set up scales of justice on the Day of Resurrection, so that no soul can be in the least wronged. Actions as small as a grain of mustard seed shall be weighed. We are sufficient as a reckoner. 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 And this is a blessed Message which We have sent down: will ye then reject it? 50
