Say: "Who guards you from Ar-Rahman by night and by day?" Yet from a mention of their Lord they turn 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 the Revelation'; but they that are deaf do not hear the call when they are warned. 45 If a blast of the torment of your Lord strikes them, they will say, "Woe to us! We have been unjust people." 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 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 And [like those earlier revelations,] this one, too, is a blessed reminder which We have bestowed from on high: will you, then, disavow it? 50
