And Muhammad ibn Hatim narrated to me, saying: Muhammad ibn Bakr narrated to us, saying: Ibn Jurayj informed us, saying: Abu al-Zubayr informed me that he heard Jabir ibn Abd Allah say: The Prophet, peace and blessings be upon him, led us in prayer on the Day of Sacrifice in Medina. Then some men went ahead and sacrificed, thinking that the Prophet, peace and blessings be upon him, had already sacrificed. So the Prophet, peace and blessings be upon him, ordered whoever had sacrificed before him to repeat with another sacrifice, and not to sacrifice until the Prophet, peace and blessings be upon him, had sacrificed.
