What did `Umar say his two companions (the Prophet (saw) and Abu Bakr) must do?
 Narrated Abu Wail:                     I sat with Shaiba in this Mosque (Al-Masjid-Al-Haram), and he said, "`Umar once sat beside me here as you are now sitting, and said, 'I feel like distributing all the gold and silver that are in it (i.e., the Ka`ba) among the Muslims'. I said, 'You cannot do that.' `Umar said, 'Why?' I said, 'Your two (previous) companions (the Prophet and Abu Bakr) did not do it. `Umar said, 'They are the two persons whom one must follow.'" (See Hadith No. 664, Vol. 2)
