Their gods have no power even to help themselves, nor are they safe from Our retribution. 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 [unto all men]: "I but warn you on the strength of divine revelation!" But the deaf [of heart] will not hearken to this call, however often 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 And We had already given Moses and Aaron the criterion and a light and a reminder for the righteous 48 Those who fear their Lord without seeing Him, while they are afraid of the Hour. 49 This is a blessed Remembrance which We have sent down. Do you disbelieve it? 50
