Say: 'Who will guard you, by night and by day from the Merciful' But no, they turn away from their Lord's remembrance. 42 Do they have some Gods who protect them from Us? Neither can they save themselves nor save their friends 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 Say, "I warn you only through the Revelation." But the deaf can hear nothing 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 And We shall set up the just balances for the Resurrection Day, so that not one soul shall be wronged anything; even if it be the weight of one grain of mustard-seed We shall produce it, and sufficient are We for reckoners. 47 And certainly We gave to Musa and Haroun the Furqan and a light and a reminder for those who would guard (against evil). 48 Those who fear their Lord without seeing Him, while they are afraid of the Hour. 49 And this [Qur'an] is a blessed message which We have sent down. Then are you with it unacquainted? 50
