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, have they gods who can defend them against Us? They shall not be able to assist themselves, nor shall they be defended from Us. 43 Nay, We gave provision to these and their fathers until life was prolonged to them. Do they not then see that We are visiting the land, curtailing it of its sides? Shall they then prevail? 44 Say, "I warn you only through the Revelation." But the deaf can hear nothing 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 On the Day of Resurrection We shall set up just scales, so that no soul shall in the least be wronged, even though it be the weight of a grain of mustard seed We will bring it; We Suffice as reckoners. 47 We gave Moses and Aaron the criterion of right and wrong and a light and reminder for the righteous, 48 Those who fear their Lord without seeing Him, while they are afraid of the Hour. 49 This is a blessed reminder that We have revealed to you. Will you then reject it? 50
