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.

It is narrated from Tawus (may Allah have mercy on him) that he possesses a book regarding blood money (diyah) upon which revelation was sent down. And whatever charity the Messenger of Allah ﷺ made obligatory or whatever blood money he made obligatory, revelation was sent down regarding it. And it has been said that the Messenger of Allah ﷺ never performed any action without Allah’s revelation; one type of revelation is that which is recited, and the other is the revelation that was sent to the Messenger of Allah ﷺ and he acted upon it.
