Say thou: who guardeth you by night and by day from the Compassionate? Yet from the remembrance of their Lord they avert themselves! 42 Or do they have lords of their own besides Us who can defend them? But they are not able to help themselves, nor can they find protection against Us. 43 Nay, We gave the good things of this life to these men and their fathers until the period grew long for them; See they not that We gradually reduce the land (in their control) from its outlying borders? Is it then they who will win? 44 Say, "I do but warn you according to revelation": But the deaf will not hear the call, (even) when they are warned! 45 And if a whiff of your Lord’s punishment were to touch them, they would certainly say, “Woe to us – we were indeed unjust!” 46 We shall fix the scales of justice on the Day of Resurrection, so that none will be wronged in the least; and even if it were equal to a mustard seed in weight We shall take it (into account). We are sufficient for computation. 47 We gave Moses and Aaron the Criterion, and gave them a light and a Remembrance for the cautious: 48 Those who fear their Lord without seeing Him, while they are afraid of the Hour. 49 This is a blessed reminder that We have revealed to you. Will you then reject it? 50
