I knew about the Islamic sanction of bestiality. Ayatollah Khomeini had this to say about the subject.
"A man can have sex with sheep, cows and camels and so on. However, he should kill the animal after he has his orgasm. He should not sell the meat to the people in his own village; however, selling the meat to the next door village should be fine."
Khomeini's "Tahrirolvasyleh" fourth volume, Darol Elm, Gom, Iran, 1990
"If one commits the act of sodomy with a cow, a ewe, or a camel, their urine and their excrement become impure, and even their milk may no longer be consumed. The animal must then be killed and as quickly as possible and burned."
