Musannaf Ibn Abi Shayba 28:816

'A'idh ibn Habib narrated to us, from Juwaybir, from al-Dahhak, who said: If a military detachment goes out and they obtain spoils of cattle or sheep, they may eat in moderation and not be extravagant. When they are brought to the military camp, it shall be among them [to be divided].
