عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ قَالَ حَفِظْنَا عَنْ ثَلَاثِينَ مِنْ أَصْحَابِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَنَّهُ قَالَ مَنْ أَعْتَقَ شِقْصًا لَهُ فِي مَمْلُوكٍ ضَمِنَ بَقِيَّتَهُ
It is narrated from Saeed bin Musayyib, he says: We have memorized this from thirty companions that the Messenger of Allah, peace and blessings be upon him, said: Whoever frees his share in a slave, he will also be responsible for the remaining price.
