Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) narrates that a man came to the service of the Prophet Muhammad (peace be upon him). The Prophet (peace be upon him) said to him: "I have been commanded that the day of Eid al-Adha is an Eid, which Allah Almighty has appointed for this Ummah." The man submitted: If I have only that animal which my father has given me as a gift, or a goat belonging to my father or my wife, which those people have given as a gift, can I slaughter it? The Prophet (peace be upon him) said: "No! However, you should trim your nails, shorten your mustache, and remove the hair below the navel, then your sacrifice will be complete in the sight of Allah Almighty."
