It is narrated from Sayyiduna Zayd bin Khalid al-Juhani (may Allah be pleased with him); he said: The Messenger of Allah (peace and blessings be upon him) distributed goats among his Companions, and he gave me a young kid (jadha'ah). I said: O Messenger of Allah! May I sacrifice it? It is only a jadha'ah of the goats. He said: "Yes." So I sacrificed it.
