Sayyiduna Jabir (may Allah be pleased with him) said: We set out with the Messenger of Allah (peace and blessings be upon him) in the state of ihram for Hajj, and women and children were with us. When we came to Makkah, we circumambulated the House of Allah and performed the sa'i between Safa and Marwah, and the Messenger of Allah (peace and blessings be upon him) ordered us: "That seven of us should share in the sacrifice of a camel and of a cow."
