What instructional practices did the Prophet Muhammad (saw) observe when he led prayers on Fridays?
 Jabir b. 'Abdullah reported:                      We used to observe (Jumu'a) prayer with the Messenger of Allah (may peace be upon him) and then we returned and gave rest to our camels used for carrying water. Hassan[ (one of the narrators) said: I asked Ja'far what time that was. He said.. It is the time when the sun passes the meridian.
