It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) entered Makkah in the year of the Conquest with a helmet (of iron) on his blessed head. When he (peace and blessings be upon him) took it off, a man came and said: "Ibn Khatal is clinging to the curtains of the Ka'bah." He (peace and blessings be upon him) said: "Kill him!"
