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 have they gods who can shield them from Us? They cannot help themselves nor can they be defended from 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 warn you only by revelation; and the deaf do not hear the call whenever 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 set up scales of justice for the Day of Judgment, so that not a soul will be dealt with unjustly in the least, and if there be (no more than) the weight of a mustard seed, We will bring it (to account): and enough are We to take account. 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 Remembrance that We have sent down; so are you now denying it? 50
