Anas bin Malik said “The Messenger of Allah(ﷺ) entered Makkah in the year of the conquest (of Makkah) wearing a helmet on his head. When he took off it a man came to him and said “Ibn Akhtal is hanging with the curtains of the Ka’bah.” He said “Kill him”. Abu Dawud said “The name of Ibn Akhtal is ‘Abd Allaah and Abu Barzat Al Aslami killed him.
