Say, "Who can protect you at night or by day from the Most Merciful?" But they are, from the remembrance of their Lord, turning away. 42 Or have they gods to defend them, other than Us? Indeed, they are unable to help themselves, neither shall they be guarded in safety from Us. 43 Nay, We have allowed these [sinners] - as [We allowed] their forebears - to enjoy the good things of life for a great length of time: but then - have they never yet seen how We visit the earth [with Our punishment,] gradually depriving it of all that is best thereon? Can they, then, [hope to] be the winners? 44 Say thou: I only warn you by the revelation; and the deaf hearken not unto the call when they are warned. 45 Were only the slightest whiff from your Lord's punishment to touch them, they would cry out: "Woe to us; we were indeed wrong-doers." 46 And We shall set balances of justice for the Day of Judgment; then no soul shall be wronged at all; and if it be but the weight of a grain of mustard-seed We shall bring it; and We suffice as Reckoners. 47 We gave Moses and Aaron the Criterion, and a light and reminder for those who take heed for themselves, 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: Will ye then reject it? 50
