NASAI-KUBRA 4930: from Ibn ʿUmar —
[Machine] The Messenger of Allah ﷺ said: "Whoever frees a slave that he co-owns, then he has freed all of him if the partner (co-owner) has enough money to cover his share, and a fair price will be set for him and paid to his partners, and his path will be left open."

الكبرى للنسائي ٤٩٣٠: عن ابن عمر —
قَالَ رَسُولُ اللهِ ﷺ «مَنْ أَعْتَقَ شِرْكًا فِي عَبْدٍ فَقَدْ أَعْتَقَ كُلَّهُ إِنْ كَانَ لِلَّذِي أَعْتَقَ نَصِيبَهُ مِنَ الْمَالِ مَا يَبْلُغُ ثَمَنَهُ يُقَامُ عَلَيْهِ قِيمَةَ عَدْلٍ فَيَدْفَعُ إِلَى شُرَكَائِهِ أَنْصِبَاءَهُمْ وَيُخَلَّى سَبِيلُهُ»
