The Prophet (ﷺ) said, "As if I were looking at him, a black person with thin legs plucking the stones of the Ka`ba one after another. "
Sahih al-Bukhari Book 25, Hadith 81
← Previous Hadith (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 (ﷺ) and Abu Bakr) did not do so.' `Umar said, They are the two persons whom I always follow.' "

Sahih al-Bukhari Book 25, Hadith 80 Next Hadith → Allah's Messenger (ﷺ) said, "Dhus-Suwaiqatain (the thin legged man) from Ethiopia will demolish the Ka`ba."
