Sayyiduna Jabir (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him) that he (peace and blessings be upon him) said: "For a hyena there is a ram, for a gazelle a goat, for a hare a one-year-old young goat, and for a jerboa a jafrah (young goat)." I asked Abu al-Zubayr (may Allah have mercy on him): What is «al-jafrah»? He said: A plump, well-grown young of a goat or sheep.
