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 Or have they gods that shall defend them apart from Us? Why, they are not able to help themselves, nor shall they be guarded in safety from 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 am warning you by God's command." But the deaf do not hear the call when they are warned. 45 And if a blast of the chastisement of your Lord were to touch them, they will certainly say: O woe to us! surely we were 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 a light and reminder for those who take heed for themselves, 48 those who fear their Lord in the unseen, also dread the Hour of Judgement. 49 And this is a blessed Reminder which We have revealed; will you then deny it? 50
