Say: 'Who shall guard you by night and in the daytime from the All-merciful?' Nay, but from the Remembrance of their Lord they are turning away. 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 generously provided them and their fathers, and they enjoyed Our provision for long. Do they not see that We are now advancing into their territory, diminishing it from different sides? Is it they, then, who will triumph?" 44 Say, "I warn you only through the Revelation." But the deaf can hear nothing when they are warned, 45 If but a breath of thy Lord's chastisement touched them, they would surely say, 'Alas for us! We were evildoers.' 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 And We verily gave Moses and Aaron the Criterion (of right and wrong) and a light and a Reminder for those who keep from evil, 48 for those who fear their Lord without seeing Him and dread the Hour (of Reckoning). 49 This is a blessed remembrance, sent down by Us; so do you deny it? 50
