Arabic (Original)
حَدَّثَنَا إِسْمَاعِيلُ حَدَّثَنَا أَيُّوبُ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ أَعْتَقَ نَصِيبًا أَوْ قَالَ شَقِيصًا لَهُ أَوْ قَالَ شِرْكًا لَهُ فِي عَبْدٍ فَكَانَ لَهُ مِنْ الْمَالِ مَا بَلَغَ ثَمَنَهُ بِقِيمَةِ الْعَدْلِ فَهُوَ عَتِيقٌ وَإِلَّا فَقَدْ عَتَقَ مِنْهُ قَالَ أَيُّوبُ كَانَ نَافِعٌ رُبَّمَا قَالَ فِي هَذَا الْحَدِيثِ وَرُبَّمَا لَمْ يَقُلْهُ فَلَا أَدْرِي أَهُوَ فِي الْحَدِيثِ أَوْ قَالَهُ نَافِعٌ مِنْ قِبَلِهِ يَعْنِي قَوْلَهُ فَقَدْ عَتَقَ مِنْهُ مَا عَتَقَ.
English Translation
Isma'il narrated to us: Ayyub narrated to us, from Nafi', from Ibn 'Umar, from the Prophet, peace and blessings be upon him: "Whoever frees his share - or he said, his portion, or he said, his part of ownership - in a slave, and he has enough wealth to cover the slave's price at a fair valuation, then he is fully freed; otherwise, only what he freed of him is freed." Ayyub said: Nafi' would sometimes say this in the hadith, and sometimes not say it, so I do not know whether it is part of the hadith or whether Nafi' said it on his own account - meaning his statement "then only what he freed of him is freed."
