Pilgrimmage (Hajj)
Bukhari :: Book 2 :: Volume 26 :: Hadith 680
Narrated Az-Zubair bin 'Arabi:
A man asked Ibn 'Umar about the touching of the Black Stone. Ibn 'Umar said, "I saw Allah's Apostle touching and kissing it." The questioner said, "But if there were a throng (much rush) round the Ka'ba and the people overpowered me, (what would I do?)" He replied angrily, "Stay in Yemen (as that man was from Yemen). I saw Allah's Apostle touching and kissing it."
