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 Yet We bestowed the good things [of life] upon their fathers for a great length of time. But do they not see how We are shrinking their borders? Is it they who will prevail? 44 Say thou: I only warn you by the revelation; and the deaf hearken not unto 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 scales of justice on the Day of Resurrection, so that no soul can be in the least wronged. Actions as small as a grain of mustard seed shall be weighed. We are sufficient as a reckoner. 47 In the past We granted to Moses and Aaron the criterion (for judgment), and a Light and a Message for those who would do right,- 48 Who fear their Lord unseen, while they are of the Hour apprehensive. 49 This is a blessed remembrance, sent down by Us; so do you deny it? 50
