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 Nay, We gave the luxuries of this life to these men and their fathers until the period grew long for them. See they not that We gradually reduce the land (in their control) from its outlying borders? Is it then they who will overcome. 44 Say, "I only warn you by revelation." But the deaf do not hear the call when they are warned. 45 If but a breath of the Wrath of thy Lord do touch them, they will then say, "Woe to us! we did wrong indeed!" 46 And We shall set balances of justice for the Day of Judgment; then no soul shall be wronged at all; and if it be but the weight of a grain of mustard-seed We shall bring it; and We suffice as Reckoners. 47 We gave Moses and Aaron the Criterion, and a light and reminder for those who take heed for themselves, 48 for those who fear their Lord without seeing Him and dread the Hour (of Reckoning). 49 This is a blessed remembrance, sent down by Us; so do you deny it? 50
