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 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 Say, "I warn you only through the Revelation." But the deaf can hear nothing when they are warned, 45 And yet, if but a breath of thy Sustainer's chastisement touches them, they are sure to cry, "Oh, woe unto us! Verily, we were evildoers!" 46 We shall set up just scales on the Day of Resurrection so that none will be wronged in the least. (We shall bring forth the acts of everyone), even if it be the weight of a grain of mustard seed. We shall suffice as Reckoners. 47 To Moses and Aaron We granted the criteria of discerning right from wrong, and We gave them the light and a reminder to the pious ones 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 remembrance, sent down by Us; so do you deny it? 50
