Say: 'Who shall guard you by night and in the daytime from the All-merciful?' Nay, but from the Remembrance of their Lord they are turning away. 42 Do they [really think that they] have deities that could shield them from Us? Those [alleged deities] are not [even] able to succour themselves: hence, neither can they [who worship them hope to] be aided [by them] 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 And if a breath of the torment of thy Lord were to touch them, they will say: woe unto us! we have been wrong-doers. 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 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
