"A man may view his wife or his slave in any part.—It is lawful for a man to look at his slave girl in any part, provided he be not related him within the prohibited degrees; and also at his wife in any part, even in the pudenda, if he pleases; because the Prophet said, “shut your eyes from all excepting your wives and female slaves.” Nevertheless, it is most becoming that a husband and wife should neither of them look at the genital parts of the other, as the Prophet has said, “when ye copulate with women of your own tribe, you must conceal as much s possible; and be not then naked, as that savours too much of the custom of asses.”"
