Musannaf Ibn Abi Shaybah 29382 — Blood money: who is liable for it?

Sayyiduna Ibn Abbas (may Allah be pleased with them both) said that the Messenger of Allah (peace and blessings be upon him) wrote a document between the Ansar and the Muhajirun: They will pay their blood money and ransom their prisoners, with the intention of goodness and of reconciliation and setting things right among the Muslims.
