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 [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 Yet We bestowed the good things [of life] upon their fathers for a great length of time. But do they not see how We are shrinking their borders? Is it they who will prevail? 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 had already given Moses and Aaron the criterion and a light and a reminder for the righteous 48 who stand in awe of their Sustainer although He is beyond the reach of human perception, and who tremble at the thought of the Last Hour. 49 This is a blessed reminder that We have revealed to you. Will you then reject it? 50
