Say thou: who guardeth you by night and by day from the Compassionate? Yet from the remembrance of their Lord they avert themselves! 42 Or have they gods who can shield them from Us? They cannot help themselves nor can they be defended from Us. 43 We have been providing these men and their fathers with the means of enjoyment for a long time. Have they not ever considered that We populated the earth and then caused many of the inhabitants to pass away? Can they have any success (in their wickedness)? 44 (Muhammad), tell them, "I am warning you by revelation alone." The deaf do not hear any call 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 But We shall set up just balance-scales on Resurrection Day, and no human being shall be wronged in the least: for though there be [in him but] the weight of a mustard-seed [of good or evil,] We shall bring it forth; and none can take count as We do! 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 Those who fear their Lord without seeing Him, while they are afraid of the Hour. 49 And this is a blessed Message which We have sent down: will ye then reject it? 50
