They have no power to aid themselves, nor can they be defended from Us. 43 Aye! We let these people and their fathers enjoy until there grew long upon them the life. Behold they not that We come unto the land diminishing it by the borders thereof? Shall they then be the victors? 44 Say thou: I only warn you by the revelation; and the deaf hearken not unto the call when they are warned. 45 yet if even a breath of your Lord's punishment touched them, they would say, "Woe to us! We were indeed wrongdoers." 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 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 Those who fear their Lord in secret and who dread the Hour (of doom). 49 And this is a blessed Reminder (the Quran) which We have sent down, will you then (dare to) deny it? 50
