'Abd al-Razzaq narrated to us, Ibn Jurayj informed us, Abu al-Zubayr informed me that he heard Jabir ibn 'Abd Allah saying: "The Prophet, peace and blessings of Allah be upon him, stood up for a funeral that passed by him until it disappeared from sight." He said: And Abu al-Zubayr also informed me that he heard Jabir saying: "The Prophet and his companions stood up for the funeral of a Jew until it disappeared from sight."
