Musnad Ahmad 30:3467

Yazid narrated to us, Al-Bara’ ibn Yazid informed us, from Abdullah ibn Shaqiq, from Abu Hurairah, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Shall I not inform you of the people of Paradise?" They said: "Yes, O Messenger of Allah." He said: "The weak and the oppressed." "Shall I not inform you of the people of the Fire?" They said: "Yes, O Messenger of Allah." He said: "Every harsh, arrogant person; they are those who do not feel for their own heads."
