Note 24 — Chapter VIII
Edward William Lane translation
Note 24. It is a general belief of the Muslims that the wicked will rise to judgment with their faces black; and hence the origin of the imprecation, "May God blacken thy face!" But it is often used to signify "May God disgrace thee!" for a person's face is said to be black when he is in any disgrace; and in the reverse case, it is said to be white.376
