Tell them, (O Muhammad): "Who protects you, during the night or the day from the Most Compassionate Lord?" And yet they turn away from the Admonition of their Lord. 42 Or have they gods that shall defend them apart from Us? Why, they are not able to help themselves, nor 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 (Muhammad), tell them, "I am warning you by revelation alone." The deaf do not hear any call when they are warned. 45 Even if a whiff of the Lord's chastisement were to touch them they would surely say: "Ah woe, alas, we were surely sinful." 46 We shall set up just scales on the Day of Resurrection so that none will be wronged in the least. (We shall bring forth the acts of everyone), even if it be the weight of a grain of mustard seed. We shall suffice as 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 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
