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 do they have gods to defend them other than Us? They are unable [even] to help themselves, nor can they be protected from Us. 43 Aye! We let these people and their fathers enjoy until there grew long upon them the life. Behold they not that We come unto the land diminishing it by the borders thereof? Shall they then be the victors? 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 We shall maintain proper justice on the Day of Judgment. No soul will be wronged the least. For a deed even as small as a mustard seed one will duly be recompensed. We are efficient in maintaining the account. 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 Those who fear their Lord in their most secret thoughts, and who hold the Hour (of Judgment) in awe. 49 And this [Qur'an] is a blessed message which We have sent down. Then are you with it unacquainted? 50
