And al-Hakam reported from Ibrahim, who said: The first to fix stipends was Sayyiduna Umar bin al-Khattab (may Allah be pleased with him), and in it he fixed the full blood money to be paid in three years, two-thirds of the blood money in two years, half in two years, one-third in one year, and whatever is less than that in its own year.
