The Prophet ﷺ said, "Whoever frees a Muslim slave, Allah will save all the parts of his body from the (Hell) Fire as he has freed the body-parts of the slave." Saʿid bin Marjana said that he narrated that Hadith to ʿAli bin Al-Husain and he freed his slave for whom ʿAbdullah bin Jaʿfar had offered him ten thousand Dirhams or one-thousand Dinars. (Using translation from Bukhārī 2517)
قَالَ رَسُولُ اللهِ ﷺ أَيُّمَا امْرِئٍ مُسْلِمٍ أَعْتَقَ امْرَأً مُسْلِمًا اسْتَنْقَذَهُ اللهُ بِكُلِّ عُضْوٍ مِنْهُ عُضْوًا مِنَ النَّارِ قَالَ سَعِيدُ ابْنُ مَرْجَانَةَ سَمِعْتُ الْحَدِيثَ فَانْطَلَقْتُ بِهِ إِلَى عَلِيِّ بْنِ الْحُسَيْنِ فَعَمِدَ إِلَى عَبْدٍ قَدْ أَعْطَاهُ بِهِ عَبْدُ اللهِ بْنُ جَعْفَرٍ عَشَرَةَ آلَافِ دِرْهَمٍ أَوْ أَلْفَ دِينَارٍ فَأَعْتَقَهُ
