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 do they have lords of their own besides Us who can defend them? But they are not able to help themselves, nor can they find protection against Us. 43 We have been providing these men and their fathers with the means of enjoyment for a long time. Have they not ever considered that We populated the earth and then caused many of the inhabitants to pass away? Can they have any success (in their wickedness)? 44 Say, "I only warn you by revelation." But the deaf do not hear the call when they are warned. 45 If but a breath of thy Lord's chastisement touched them, they would surely say, 'Alas for us! We were evildoers.' 46 And We shall set up the just balances for the Resurrection Day, so that not one soul shall be wronged anything; even if it be the weight of one grain of mustard-seed We shall produce it, and sufficient are We for reckoners. 47 In the past We granted to Moses and Aaron the criterion (for judgment), and a Light and a Message for those who would do right,- 48 (For) those who fear their Lord in secret and they are fearful of the hour. 49 And this is a blessed Remembrance that We have sent down; so are you now denying it? 50
