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 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 do but warn you according to revelation": But the deaf will not hear the call, (even) when 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 We shall maintain proper justice on the Day of Judgment. No soul will be wronged the least. For a deed even as small as a mustard seed one will duly be recompensed. We are efficient in maintaining the account. 47 We gave Moses and Aaron the criterion of right and wrong and a light and reminder for the righteous, 48 those who fear their Lord in the unseen, also dread the Hour of Judgement. 49 This is a blessed reminder that We have revealed to you. Will you then reject it? 50
