'Abdullah ibn 'Umar ibn Aban narrated to us, 'Abdah narrated to us, from Hisham ibn 'Urwah, from Musa ibn 'Uqbah, from 'Abdullah ibn 'Amr al-Awdi, from 'Abdullah ibn Mas'ud, who said: The Messenger of Allah (ﷺ) said: "Shall I not inform you of whom the Fire is forbidden, or who is forbidden to the Fire? [It is] every gentle, approachable, easy-going person."
