Take account of yourself before you are taken to account, and weigh yourself before you are weighed, for it would be easier on your Accounting tomorrow if you do so today. Adorn yourself for the great exposure, the day you shall be exposed and not a secret of yours will remain hidden.
—‘Umar ibn al-Khaṭṭāb [d. 23H/644CE] in his inaugural address upon becoming Caliph
[Muṣannaf Ibn Abī Shaybah, Kanz al-‘Ummāl]
