Say: "Who guards you from Ar-Rahman by night and by day?" Yet from a mention of their Lord they turn away. 42 Or do they have gods to defend them other than Us? They are unable [even] to help themselves, nor can they be protected 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: I warn you only by revelation; and the deaf do not hear the call whenever they are warned. 45 And if a breath of thy Lord's punishment were to touch them, they assuredly would say: Alas for us! Lo! we were wrong-doers. 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 To Moses and Aaron We granted the criteria of discerning right from wrong, and We gave them the light and a reminder to the pious ones 48 Who fear their Lord unseen, while they are of the Hour apprehensive. 49 This (Quran) which We have revealed is a blessed reminder. Will you then deny it? 50
