Musnad Ahmad 30:1700

Yahya ibn Ishaq narrated to us, he said: Al-Bara’ ibn Abdullah informed us, from Abdullah ibn Shaqiq, from Abu Hurairah, he 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 are the weak and the oppressed. Shall I not inform you of the people of the Fire? Every harsh, arrogant person."
