Imam Ja'far al-Sadiq narrates from his father (Imam Muhammad al-Baqir) the statement of Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both): We used to perform the Friday prayer behind the Prophet Muhammad (peace be upon him), then we would return and let our water-carrying camels rest. (Imam al-Baqir narrates:) I asked: Which hour was this? He replied: The time when the sun had declined.
