Abu Hurairah reported the Prophet (ﷺ) as saying:If anyone emancipates his share in a slave, he is to be completely emancipated by his money if he has money. But if he has no money, a fair price for the slave should be fixed, and the slave is required to work for his master according to the proportion of his price, but he must not be overburdened.Abu Dawud said: In the version of both the narrators the words are "he will be required to work and must not be overburdened". This is the version of 'Ali.
حَدَّثَنَا نَصْرُ بْنُ عَلِيٍّ، أَخْبَرَنَا يَزِيدُ، - يَعْنِي ابْنَ زُرَيْعٍ - ح وَحَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا مُحَمَّدُ بْنُ بِشْرٍ، - وَهَذَا لَفْظُهُ - عَنْ سَعِيدِ بْنِ أَبِي عَرُوبَةَ، عَنْ قَتَادَةَ، عَنِ النَّضْرِ بْنِ أَنَسٍ، عَنْ بَشِيرِ بْنِ نَهِيكٍ، عَنْ أَبِي هُرَيْرَةَ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ " مَنْ أَعْتَقَ شِقْصًا لَهُ - أَوْ شَقِيصًا لَهُ - فِي مَمْلُوكٍ فَخَلاَصُهُ عَلَيْهِ فِي مَالِهِ إِنْ كَانَ لَهُ مَالٌ فَإِنْ لَمْ يَكُنْ لَهُ مَالٌ قُوِّمَ الْعَبْدُ قِيمَةَ عَدْلٍ ثُمَّ اسْتُسْعِيَ لِصَاحِبِهِ فِي قِيمَتِهِ غَيْرَ مَشْقُوقٍ عَلَيْهِ " . قَالَ أَبُو دَاوُدَ فِي حَدِيثِهِمَا جَمِيعًا " فَاسْتُسْعِيَ غَيْرَ مَشْقُوقٍ عَلَيْهِ " . وَهَذَا لَفْظُ عَلِيٍّ .
