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 Do they have other deities who can defend them against Us? They cannot even help themselves, neither can they be aided against Us. 43 Nay, We gave the luxuries of this life to these men and their fathers until the period grew long for them. See they not that We gradually reduce the land (in their control) from its outlying borders? Is it then they who will overcome. 44 (Muhammad), tell them, "I am warning you by revelation alone." The deaf do not hear any 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 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 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 such as fear God in the Unseen, trembling because of the Hour. 49 This is a blessed remembrance, sent down by Us; so do you deny it? 50
