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 thou: I only warn you by the revelation; and the deaf hearken not unto the call when they are warned. 45 And if a blast of the chastisement of your Lord were to touch them, they will certainly say: O woe to us! surely we were unjust. 46 And We shall set up the just balances for the Resurrection Day, so that not one soul shall be wronged anything; even if it be the weight of one grain of mustard-seed We shall produce it, and sufficient are We for 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 without seeing Him, while they are afraid of the Hour. 49 And this [Qur'an] is a blessed message which We have sent down. Then are you with it unacquainted? 50
