Hadith 1295B12

قَالَ مَالِك: فَإِنْ جَهِلَ ذَلِكَ حَتَّى يُؤَدِّيَ الْمُكَاتَبُ، أَوْ قَبْلَ أَنْ يُؤَدِّيَ رَدَّ إِلَيْهِ الَّذِي كَاتَبَهُ مَا قَبَضَ مِنَ الْمُكَاتَبِ، فَاقْتَسَمَهُ هُوَ وَشَرِيكُهُ عَلَى قَدْرِ حِصَصِهِمَا، وَبَطَلَتْ كِتَابَتُهُ وَكَانَ عَبْدًا لَهُمَا عَلَى حَالِهِ الْأُولَى .¤
Imam Malik, may Allah have mercy on him, said: If this partner does not know this issue, and he makes his share a mukatab and receives all or part of the price of the contract of manumission, then whatever has been received should be divided between him and his partner according to their respective shares. The contract of manumission will be invalid, and the mukatab will remain a slave as before.
