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 have they aliha (gods) who can guard them from Us? They have no power to help themselves, nor can they be protected from Us (i.e. from Our Torment). 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 But We shall set up just balance-scales on Resurrection Day, and no human being shall be wronged in the least: for though there be [in him but] the weight of a mustard-seed [of good or evil,] We shall bring it forth; and none can take count as We do! 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 the unseen, also dread the Hour of Judgement. 49 And this is a blessed Message which We have sent down: will ye then reject it? 50
