Ibn Jurayj (may Allah have mercy on him) narrates that Ibn Tawus said to me that my father has a book in which the mention of those blood monies (diyah) is found upon which revelation was sent down. And whatever the Messenger of Allah (ﷺ) made obligatory regarding blood monies and zakat, revelation was sent down about it.
