Say: Who guards you by night and by day from the Beneficent Allah? Nay, they turn aside at the mention of their Lord. 42 Or, have they gods who can defend them against Us? They shall not be able to assist themselves, nor shall they be defended from Us. 43 We allowed them and their fathers time to enjoy till the very end of their lives. Do they not see Us advancing into the land, reducing its frontiers? Would they still prevail? 44 (Muhammad), tell them, "I am warning you by revelation alone." The deaf do not hear any call when they are warned. 45 If a blast of the torment of your Lord strikes them, they will say, "Woe to us! We have been unjust people." 46 And We set a just balance for the Day of Resurrection so that no soul is wronged in aught. Though it be of the weight of a grain of mustard seed, We bring it. And We suffice for reckoners. 47 And assuredly We vcuchsafed unto Musa and Harun the distinction and illumination and an admonition for the God-fearing. 48 those who fear their Lord in the unseen, also dread the Hour of Judgement. 49 This (Quran) which We have revealed is a blessed reminder. Will you then deny it? 50
