The Prophet ﷺ said, "If one manumits his share of a common slave (Abd), and he has money sufficient to free the remaining portion of the price of the slave (justly estimated), then he should free the slave completely by paying the rest of his price; otherwise the slave is freed partly. "  

قَالَ النَّبِيُّ ﷺ مَنْ أَعْتَقَ نَصِيبًا لَهُ مِنَ الْعَبْدِ فَكَانَ لَهُ مِنَ الْمَالِ مَا يَبْلُغُ قِيمَتَهُ يُقَوَّمُ عَلَيْهِ قِيمَةَ عَدْلٍ وَأُعْتِقَ مِنْ مَالِهِ وَإِلاَّ فَقَدْ عَتَقَ مِنْهُ  

He who gives up his share in a slave, and he has money enough to meet the full price, a fair price for him should be fixed; otherwise be has emancipated him to the extent that he has emancipated.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ أَعْتَقَ نَصِيبًا لَهُ فِي عَبْدٍ فَكَانَ لَهُ مِنَ الْمَالِ قَدْرُ مَا يَبْلُغُ قِيمَتَهُ قُوِّمَ عَلَيْهِ قِيمَةَ عَدْلٍ وَإِلاَّ فَقَدْ عَتَقَ مِنْهُ مَا عَتَقَ  

Malik related to me from Nafi from Abdullah ibn Umar that the Messenger of Allah ﷺsaid, "If a man frees his share of a slave and has enough money to cover the full price of the slave justly evaluated for him, he must buy out his partners so that the slave is completely freed. If he doesn't have the money, he partially frees him.  

أنَّ رَسُولَ اللَّهِ ﷺ قالَ: «مَن أعْتَقَ شِرْكًا لَهُ فِي عَبْدٍ. فَكانَ لَهُ مالٌ يَبْلُغُ ثَمَنَ العَبْدِ، قُوِّمَ عَلَيْهِ قِيمَةَ العَدْلِ. فَأعْطى شُرَكاءَهُ حِصَصَهُمْ. وعَتَقَ عَلَيْهِ العَبْدُ. وإلّا فَقَدْ عَتَقَ مِنهُ ما عَتَقَ»  

[Machine] The Prophet Muhammad ﷺ said, "Whoever frees a slave that belongs to him, if he has enough wealth to cover its value, he should estimate its value and set it free accordingly. Otherwise, he has freed whatever he has freed."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَنْ أَعْتَقَ شَقِيصًا لَهُ فِي عَبْدٍ فَإِنْ كَانَ لَهُ مِنَ الْمَالِ مَا يَبْلُغُ قِيمَتَهُ قُوِّمَ عَلَيْهِ قِيمَةَ عَدْلٍ وَإِلَّا فَقَدْ أَعْتَقَ مَا أَعْتَقَ
