Tell them, (O Muhammad): "Who protects you, during the night or the day from the Most Compassionate Lord?" And yet they turn away from the Admonition 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 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 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 such as fear God in the Unseen, trembling because of the Hour. 49 And this is a blessed reminder that We have sent down. Will you then deny it? 50
