Jubayr bin Nufayr (may Allah have mercy on him) narrates from Sayyiduna Thawban (may Allah be pleased with him), the freed slave of the Messenger of Allah (peace and blessings be upon him), that the Messenger of Allah (peace and blessings be upon him) slaughtered his sacrifice and said: "O Thawban! Prepare this sheep for us and cook it well." He said: I kept feeding him from it until we reached Madinah.
