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 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 Say thou: I only warn you by the revelation; and the deaf hearken not unto the call 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 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 a light and reminder for those who take heed for themselves, 48 Who fear their Lord unseen, while they are of the Hour apprehensive. 49 And this is a blessed Message which We have sent down: will ye then reject it? 50
