Sahih Bukhari Volume 2, Book 26, Hadith Number 664.
Narated By Abu Wail : (One day) I sat along with Shaiba on the chair inside the Ka’ba. 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 Ka’ba) 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.'”
