Say: Who guardeth you in the night or in the day from the Beneficent? Nay, but they turn away from mention of their Lord! 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 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: 'I warn you only by the Revelation'; but they that are 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 shall set up balances of justice on the Day of Resurrection, then none will be dealt with unjustly in anything. And if there be the weight of a mustard seed, We will bring it. And Sufficient are We as Reckoners. 47 To Moses and Aaron We granted the criteria of discerning right from wrong, and We gave them the light and a reminder to the pious ones 48 who stand in awe of their Sustainer although He is beyond the reach of human perception, and who tremble at the thought of the Last Hour. 49 And this is a blessed Reminder which We have revealed; will you then deny it? 50
