Say: 'Who will guard you, by night and by day from the Merciful' But no, they turn away from their Lord's remembrance. 42 Do they have any gods who would protect them against Us? They have no power even to help themselves; nor do they enjoy Our support. 43 Yet We bestowed the good things [of life] upon their fathers for a great length of time. But do they not see how We are shrinking their borders? Is it they who will prevail? 44 Tell them: "I only warn you by the Revelation." But the deaf do not hear the cry when they are warned. 45 And if [as much as] a whiff of the punishment of your Lord should touch them, they would surely say, "O woe to us! Indeed, we have been wrongdoers." 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: Will ye then reject it? 50
