Say: 'Who shall guard you by night and in the daytime from the All-merciful?' Nay, but from the Remembrance of their Lord they are turning away. 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 Say: "I am warning you by God's command." But the deaf do not hear the call when they are warned. 45 And if a whiff of your Lord’s punishment were to touch them, they would certainly say, “Woe to us – we were indeed unjust!” 46 And We shall set up balances of justice on the Day of Resurrection, then none will be dealt with unjustly in anything. And if there be the weight of a mustard seed, We will bring it. And Sufficient are We as Reckoners. 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 in their most secret thoughts, and who hold the Hour (of Judgment) in awe. 49 And this is a blessed reminder that We have sent down. Will you then deny it? 50
