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 Can their gods protect them against Us? Their gods have no power even to help themselves, nor are they safe from Our retribution. 43 Nay, We gave the good things 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 win? 44 Say: 'I warn you only by the Revelation'; but they that are deaf do not hear 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 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 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 reminder that We have revealed to you. Will you then reject it? 50
