Say: "Who guards you from Ar-Rahman by night and by day?" Yet from a mention of their Lord they 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 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 SAY [unto all men]: "I but warn you on the strength of divine revelation!" But the deaf [of heart] will not hearken to this call, however often 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 shall set balances of justice for the Day of Judgment; then no soul shall be wronged at all; and if it be but the weight of a grain of mustard-seed We shall bring it; and We suffice as Reckoners. 47 And assuredly We vcuchsafed unto Musa and Harun the distinction and illumination and an admonition for the God-fearing. 48 (For) those who fear their Lord in secret and they are fearful of the hour. 49 And this is a blessed Reminder (the Quran) which We have sent down, will you then (dare to) deny it? 50
