Musannaf Ibn Abi Shayba 18:1038

Abu Bakr narrated to us, he said: Yazid ibn Harun narrated to us, he said: Hushaym narrated to us, from Isma'il ibn Salim, from al-Sha'bi, he said: "Whoever kills two men is a tyrant (jabbar)." And he recited: "Do you intend to kill me as you killed a person yesterday? You only intend to be a tyrant in the land and you do not intend to be of the reformers."
