Yahya related to me from Malik from Yahya ibn Said that he heardSaid ibn al-Musayyab say, "When people in military expeditions dividedthe spoils, they made a camel equal to ten sheep."Malik saidabout the paid labourer in military expeditions, "If he is present atthe battle and is with the people in the battle and he is a free man,he has his share. If he is not present, he has no share."Malik summed up, "I think that the booty is only divided among freemen who have been present at the battle. "
