Say: "Who can keep you safe by night and by day from (the Wrath of) (Allah) Most Gracious?" Yet they turn away from the mention of their Lord. 42 Or have they gods that shall defend them apart from Us? Why, they are not able to help themselves, nor shall they be guarded in safety from Us. 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 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 And We shall set up balances of justice on the Day of Resurrection, then none will be dealt with unjustly in anything. And if there be the weight of a mustard seed, We will bring it. And Sufficient are We as Reckoners. 47 We gave Moses and Aaron the Criterion, and a light and reminder for those who take heed for themselves, 48 Who are fearful of their Lord inwardly and dread the Hour. 49 And this is a blessed Remembrance that We have sent down; so are you now denying it? 50
