al-Hasan bin Musa al-'Ashayb الحسن بن موسى الأشيب · The Chapters on Blood Money

“Whoever suffers from killing or wounding, has the choice of three things, and if he wants the fourth then restrain him. He may kill (the killer), or forgive him, or take the blood money. Whoever accepts any of these (options), then kills (the killer) after that will have the fire of hell to abide therein forever.”
