Sayyiduna Ibn Abbas (may Allah be pleased with them both) narrated from the Messenger of Allah (peace and blessings be upon him), he (peace be upon him) said: "If a mukatab (a slave with a contract of manumission) is killed, the blood money for the portion he has paid for his freedom will be given as that of a free man, and for the portion he remains a slave, the blood money will be given as that of a slave."
