Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "The first person to set free she-camels for the sake of other than Allah and to worship idols was 'Amr bin 'Amir, who is the ancestor of the Khuza'ah tribe. I saw him dragging his intestines in Hell."
