It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that the Messenger of Allah (peace and blessings be upon him) said: "When a slave is jointly owned by several partners and one of them frees him, the slave will be valued at the highest price against him (the one who freed him); then he will pay his price as compensation, and the slave will be freed."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated these two hadiths from Amr bin Shu'ayb (may Allah have mercy on him) except al-Muthanna bin al-Sabbah (may Allah have mercy on him)."
