Say: 'Who will guard you, by night and by day from the Merciful' But no, they turn away from their Lord's remembrance. 42 Or have they gods that can guard them from Us? They have no power to aid themselves, nor can they be defended from Us. 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 only warn you by revelation." But the deaf do not hear the 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 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 Surely We had granted to Moses and Aaron the Criterion (between right and wrong), and Light and Admonition for the good of the God-fearing, 48 Who fear their Lord unseen, while they are of the Hour apprehensive. 49 And this is a blessed Reminder (the Quran) which We have sent down, will you then (dare to) deny it? 50
