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 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 (Muhammad), tell them, "I am warning you by revelation alone." The deaf do not hear any call when they are warned. 45 But if just a breath of your Lord's punishment were to touch them, they would say: 'Woe for us, we were harmdoers' 46 And We shall set up balances of justice on the Day of Resurrection, then none will be dealt with unjustly in anything. And if there be the weight of a mustard seed, We will bring it. And Sufficient are We as Reckoners. 47 And certainly We gave to Musa and Haroun the Furqan and a light and a reminder for those who would guard (against evil). 48 for those who fear their Lord without seeing Him and dread the Hour (of Reckoning). 49 This (Quran) which We have revealed is a blessed reminder. Will you then deny it? 50
