حَدَّثَنَا هُشَيْمٌ أَنْبَأَنَا يَحْيَى بْنُ سَعِيدٍ عَنْ نَافِعٍ عَنْ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مَنْ أَعْتَقَ نَصِيبًا لَهُ فِي مَمْلُوكٍ كُلِّفَ أَنْ يُتِمَّ عِتْقَهُ بِقِيمَةِ عَدْلٍ

It was narrated from Ibn Umar that the Messenger of Allah (PBUH) said: "Whoever manumits his share of a slave is responsible for completing his manumission on the basis of fair value."
