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 do they have lords of their own besides Us who can defend them? But they are not able to help themselves, nor can they find protection against 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 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 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, and gave them a light and a Remembrance for the cautious: 48 who stand in awe of their Sustainer although He is beyond the reach of human perception, and who tremble at the thought of the Last Hour. 49 This is a Blessed Admonition that We have revealed. Are you, then, going to reject it? 50
