Silsilah Sahihah

It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "A flame from the Fire of Hell will come out and speak, saying: Three types of people have been entrusted to me: (1) Every tyrant and arrogant person, (2) The one who associates another deity with Allah, and (3) The person who kills someone unjustly. That flame will envelop them and throw them into the severities and hardships of Hell."
