The Prophet (may Allah's peace and blessings be upon him) circumambulated the Ka‘bah in the Farewell Hajj on the back of a camel, touching the Corner with a crook.
Authentic hadithعن عبد الله بن عباس رضي الله عنهما قال: «طَافَ النبيُّ -صلَّى الله عليه وسلَّم- فِي حَجَّةِ الوَدَاعِ على بَعِير، يَستَلِم الرُّكنَ بِمِحجَن».
‘Abdullāh ibn ‘Abbās (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him) circumambulated the Kab‘ah in the Farewell Hajj on the back of a camel, touching the Corner with a crook.
Explanation
As the Prophet (may Allah's peace and blessings be upon him) circumambulated the Ka‘bah in his Farewell pilgrimage, people jostled to watch him doing the rites or to only see his noble face. Merciful and just, the Prophet (may Allah's peace and blessings be upon him) rode a camel so that everyone could see him. He had a hooked stick whereby he touched the Corner and then kissed the stick, as we know from the narration of Muslim.
