Lady Aisha (may Allah be pleased with her) narrates that when we were in Mina, some beef was brought to me. So I asked, "What meat is this?" The companions replied, "This is beef; the Messenger of Allah (peace and blessings be upon him) has offered a cow as a sacrifice on behalf of his noble wives."
