(2) باب فِي بَيْعِ الْمُكَاتَبِ إِذَا فُسِخَتِ الْكِتَابَةُ
'Aishah said:
Barirah came seeking my help to purchase her freedom. She said: I have arranged with my people to buy my freedom for nine 'uqiyahs: one to be paid annually. So help me. She ('Aishah) said: If your people are willing that I should count them ('uqiyahs) out to them all at one time and set you free and that I shall have the right to inherit from you, I shall do so. She then went to her people. The narrator then transmitted the rest of the tradition like the version of al-Zuhri. He added to the wordings of the Prophet (ﷺ) in the last: What is the matter with people that one of you says: Set free, O so-and-so, and the right of inheritance belongs to me. The right of inheritance belongs to the one who has set a person free.
