Say: "Who could protect you, by night or by day, from the Most Gracious?" And yet, from a remembrance of their Sustainer do they stubbornly turn 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 Yet We bestowed the good things [of life] upon their fathers for a great length of time. But do they not see how We are shrinking their borders? Is it they who will prevail? 44 Say: 'I warn you only by the Revelation'; but they that are deaf do not hear the call when they are warned. 45 If but a breath of the Wrath of thy Lord do touch them, they will then say, "Woe to us! we did wrong indeed!" 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, INDEED, We vouchsafed unto Moses and Aaron [Our revelation as] the standard by which to discern the true from the false, and as a [guiding] light and a reminder for the God-conscious 48 These who fear their Lord unseen, and who are of the Hour fearful. 49 This is a blessed remembrance, sent down by Us; so do you deny it? 50
