Sahih Bukhari, Chapter: Pilgrimage (Hajj)

(One day) I sat along with Shaiba on the chair inside the Kaaba. He (Shaiba) said, "No doubt, Umar sat at this place and said, 'I intended not to leave any yellow (i.e. gold) or white (i.e. silver) (inside the Kaaba) undistributed.' I said (to 'Umar), 'But your two companions (i.e. The Prophet and Abu Bakr) did not do so.' 'Umar said, They are the two persons whom I always follow.' "
