'Abd al-Razzaq narrated to us, Ma'mar narrated to us, from al-Zuhri, from Ibn al-Musayyib, from Abu Hurayrah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "In the end of time, the one with the two thin shins will appear against the Ka'bah." He said: I think he said: "And he will demolish it."
