Kharijah bin al-Harith narrates from his father, al-Harith bin Rafi' bin Makith al-Juhani, that he asked Jabir bin Abdullah (may Allah be pleased with them both), the Companion of the Messenger of Allah (peace and blessings be upon him): We have goats and slaves, and they beat down leaves for their goats from this habalah fruit. Kharijah said: It is the fruit of the samurah (acacia) tree. Jabir (may Allah be pleased with him) said: "No, and again no! The leaves of the reserve (hima) of the Messenger of Allah (peace and blessings be upon him) are not to be beaten down, nor its trees cut; but shake them down gently." Jabir (may Allah be pleased with him) said: "The Messenger of Allah (peace and blessings be upon him) — I think he said — used to forbid cutting the masad." Jabir said: The masad is the axle-pin of a pulley. Ibn Abi Uways said: The reserve is around Madinah.
