Say: "Who can keep you safe by night and by day from (the Wrath of) (Allah) Most Gracious?" Yet they turn away from the mention of their Lord. 42 Do they have some Gods who protect them from Us? Neither can they save themselves nor save their friends from Us. 43 Nay, but Ourselves gave these and their fathers enjoyment of days, until their life had lasted long while upon them. What, do they not see how We come to the land, diminishing it in its extremities? Or are they the victors? 44 Tell them: "I only warn you by the Revelation." But the deaf do not hear the cry 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 And We set a just balance for the Day of Resurrection so that no soul is wronged in aught. Though it be of the weight of a grain of mustard seed, We bring it. And We suffice for reckoners. 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 who fear their unseen Lord and are anxious about the Day of Judgment. 49 And this is a blessed Remembrance that We have sent down; so are you now denying it? 50
