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 defend them against Us? They shall not be able to assist themselves, nor shall they be defended from Us. 43 Nay, We gave provision to these and their fathers until life was prolonged to them. Do they not then see that We are visiting the land, curtailing it of its sides? Shall they then prevail? 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 [as much as] a whiff of the punishment of your Lord should touch them, they would surely say, "O woe to us! Indeed, we have been wrongdoers." 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 We gave Moses and Aaron the criterion of right and wrong and a light and reminder for the righteous, 48 These who fear their Lord unseen, and who are of the Hour fearful. 49 This is a blessed reminder that We have revealed to you. Will you then reject it? 50
