وَحَدَّثَنِي مَالِكٌ، أَنَّهُ بَلَغَهُ أَنَّ عُرْوَةَ بْنَ الزُّبَيْرِ، وَسُلَيْمَانَ بْنَ يَسَارٍ، كَانَا يَقُولاَنِ الْمُكَاتَبُ عَبْدٌ مَا بَقِيَ عَلَيْهِ مِنْ كِتَابَتِهِ شَىْءٌ ‏.‏ قَالَ مَالِكٌ وَهُو رَأْيِي ‏.‏ قَالَ مَالِكٌ فَإِنْ هَلَكَ الْمُكَاتَبُ وَتَرَكَ مَالاً أَكْثَرَ مِمَّا بَقِيَ عَلَيْهِ مِنْ كِتَابَتِهِ وَلَهُ وَلَدٌ وُلِدُوا فِي كِتَابَتِهِ أَوْ كَاتَبَ عَلَيْهِمْ وَرِثُوا مَا بَقِيَ مِنَ الْمَالِ بَعْدَ قَضَاءِ كِتَابَتِهِ ‏.‏

Malik related to me that he had heard that Urwa ibn az-Zubayr andSulayman ibn Yasar said, "The mukatab is a slave as long as any of hiskitaba remains to be paid." Malik said, "This is my opinionas well." Malik said, "If a mukatab dies and leaves moreproperty than what remains to be paid of his kitaba and he haschildren who were born during the time of his kitaba or whose kitabahas been written as well, they inherit any property that remains afterthe kitaba has been paid."
