Musannaf Ibn Abi Shaybah 29385 — Blood money: who is liable for it?

Ibrahim said that Sayyiduna Ali (may Allah be pleased with him) and Sayyiduna al-Zubayr (may Allah be pleased with him) came before Sayyiduna Umar (may Allah be pleased with him) with the matter of the wala' (right of patronage) over the freed slaves of Sayyidah Safiyyah (may Allah be pleased with her). Sayyiduna Umar decided the inheritance in favor of Sayyiduna al-Zubayr and made the blood money binding on Sayyiduna Ali.
