Mukhtasar Bukhari

Narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings of Allah be upon him) entered Makkah in the year of the conquest of Makkah, there was a helmet on his blessed head. When he (peace be upon him) removed it, a man came to him and said: "The wretched disbeliever named Ibn Khatal is clinging to the curtains of the Ka'bah." The Prophet (peace be upon him) said: "Kill him there."
