It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that he said: "A man from among the Bedouins died and he had no 'asabah (male agnatic heir), but he had a freed slave whom he himself had set free. The matter was brought to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) asked: 'Did he not use to be angry at his anger and pleased at his pleasure?' They said: 'Yes!' So he (peace and blessings be upon him) made him the heir of the wealth of his mawla (the master who had freed him)."
No one narrated this hadith from Abd al-Karim (may Allah have mercy on him) except Abu Hamzah (may Allah have mercy on him), and Ali bin al-Hasan (may Allah have mercy on him) is alone in narrating it.
