[Machine] Indeed, a man had freed a portion of a slave for himself, but the Prophet ﷺ did not guarantee him. Ahmad ibn Hanbal said: "It is indeed with the letter 'ta'," meaning the extra burden (of freeing the slave). And Shu'bah al-Athqah did not differentiate between the letter "ta" and "tha." The scholar, may Allah have mercy on him, said: "This does not contradict what has been mentioned previously in the hadiths, as it pertains to the one who frees their portion of the slave, they are not responsible for the remaining portion. And Allah knows best."  

أَنَّ رَجُلًا أَعْتَقَ نَصِيبًا لَهُ مِنْ مَمْلُوكٍ فَلَمْ يَضْمَنْهُ النَّبِيُّ ﷺ قَالَ أَحْمَدُ بْنُ حَنْبَلٍ إِنَّمَا هُوَ بِالتَّاءِ يَعْنِي التِّلِبَّ وَكَانَ شُعْبَةُ أَلْثَغَ لَمْ يُبَيِّنِ التَّاءَ مِنَ الثَّاءِ قَالَ الشَّيْخُ رَحِمَهُ اللهُ وَهَذَا لَا يُخَالِفُ مَا مَضَى مِنَ الْأَحَادِيثِ وَإِنَّمَا هُوَ فِي الْمُعْسِرِ إِذَا أَعْتَقَ نَصِيبَهُ مِنْ مَمْلُوكٍ فَلَا يَضْمَنُ الْبَاقِي وَاللهُ أَعْلَمُ
