Musannaf Ibn Abi Shaybah 29230 — Over how long is blood money paid?

Al-Sha'bi said: The first to fix stipends was Sayyiduna Umar bin al-Khattab (may Allah be pleased with him), and 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 is to be paid in that same year.
