Say: 'Who will guard you, by night and by day from the Merciful' But no, they turn away from their Lord's remembrance. 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 luxuries 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 overcome. 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 breath of thy Lord's punishment were to touch them, they assuredly would say: Alas for us! Lo! we were wrong-doers. 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 These who fear their Lord unseen, and who are of the Hour fearful. 49 And this is a blessed Remembrance that We have sent down; so are you now denying it? 50
