Hadith 1011

Ibn 'Umar (RAA) narrated that The Messenger of Allah (ﷺ) said: “Three types of people are most hated by Allah, the Almighty: whoever kills another in the Sacred area of Haram (Sanctuary), whoever kills anyone other than the one who killed him or whoever kills anyone in revenge as in times of Jahiliyah (pre-Islamic times).” Related by Ibn Hibban. And it's basic meaning is in Al-Bukhari from the narration of Ibn 'Abbas.
