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 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 Nay, We generously provided them and their fathers, and they enjoyed Our provision for long. Do they not see that We are now advancing into their territory, diminishing it from different sides? Is it they, then, who will triumph?" 44 Say: 'I warn you only by the Revelation' But the deaf hear nothing 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 set up scales of justice on the Day of Resurrection, so that no soul can be in the least wronged. Actions as small as a grain of mustard seed shall be weighed. We are sufficient as a reckoner. 47 And We verily gave Moses and Aaron the Criterion (of right and wrong) and a light and a Reminder for those who keep from evil, 48 for those who fear their Lord without seeing Him and dread the Hour (of Reckoning). 49 This is a blessed Reminder that we have revealed: Will ye then reject it? 50
