Musnad Ahmad 25:1283

Muhammad ibn Ja‘far and Abu ‘Abd al-Samad narrated to us, they said: Sa‘id narrated to us, from Qatadah, from ‘Ikrimah, from Ibn ‘Abbas: "That the Messenger of Allah, peace and blessings of Allah be upon him, forbade the *mujaththamah* (an animal tied up and used as a target for shooting) and the *jallalah* (an animal that eats filth)." Abu ‘Abd al-Samad said: "He forbade the milk of the *jallalah*." "And that one should drink directly from the mouth of the waterskin."
