Translations:Yirmi Dördüncü Lem'a/24/en

By nature, men do not feel any lust towards those within the stipulated degrees of kinship like their sisters, because, since such relatives’ faces induce kindness and licit love due to their close kinship, it nullifies any sexual or lusty inclinations. But to leave uncovered parts of the body which according to the Shari‘a it is not permissible to expose to close relatives like the legs, may awaken extremely ugly feelings in men of low character. For the face of a close relative reminds the man of their close kinship and does not resemble the face of someone outside the degrees of kinship, but a bare leg is the same as that of canonical strangers. The leg does bear any distinguishing mark to recall the close kinship of its owner, so may arouse carnal feelings in the man. To look on such things is so degenerate as to make one’s hair stand on end.
