Say: Who guards you by night and by day from the Beneficent Allah? Nay, they turn aside at the mention of their Lord. 42 Or have they gods that can guard them from Us? They have no power to aid themselves, nor can they be defended from Us. 43 But, [on the contrary], We have provided good things for these [disbelievers] and their fathers until life was prolonged for them. Then do they not see that We set upon the land, reducing it from its borders? So it is they who will overcome? 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 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 We shall set up scales of justice on the Day of Resurrection, so that no soul can be in the least wronged. Actions as small as a grain of mustard seed shall be weighed. We are sufficient as a reckoner. 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 their most secret thoughts, and who hold the Hour (of Judgment) in awe. 49 This is a blessed Reminder that we have revealed: Will ye then reject it? 50
