ABUDAWUD 3943:
from Ibn ʿUmar —
If anyone emancipates his share in a slave, he should emancipate him completely if he has enough money to pay the full price ; but if he has none, he will be emancipated to the extent of his share.
أبو داود ٣٩٤٣:
عن ابن عمر —
قَالَ رَسُولُ اللَّهِ ﷺ مَنْ أَعْتَقَ شِرْكًا مِنْ مَمْلُوكٍ لَهُ فَعَلَيْهِ عِتْقُهُ كُلُّهُ إِنْ كَانَ لَهُ مَا يَبْلُغُ ثَمَنَهُ وَإِنْ لَمْ يَكُنْ لَهُ مَالٌ عَتَقَ نَصِيبُهُ
