"Any Muslim man who frees a Muslim man, then it is his salvation from the Fire - each of his limbs suffices for a limb of himself. And any Muslim man that frees two Muslim women, then are his salvation from the Fire - each of their limbs suffices for a limb of himself. And any Muslim woman that frees a Muslim woman, then she is her salvation from the Fire - each of her limb suffices for a limb of herself."  

عَنْ أَبِي أُمَامَةَ وَغَيْرِهِ مِنْ أَصْحَابِ النَّبِيِّ ﷺ عَنْ النَّبِيِّ ﷺ قَالَ أَيُّمَا امْرِئٍ مُسْلِمٍ أَعْتَقَ امْرَأً مُسْلِمًا كَانَ فَكَاكَهُ مِنْ النَّارِ يُجْزِي كُلُّ عُضْوٍ مِنْهُ عُضْوًا مِنْهُ وَأَيُّمَا امْرِئٍ مُسْلِمٍ أَعْتَقَ امْرَأَتَيْنِ مُسْلِمَتَيْنِ كَانَتَا فَكَاكَهُ مِنْ النَّارِ يُجْزِي كُلُّ عُضْوٍ مِنْهُمَا عُضْوًا مِنْهُ وَأَيُّمَا امْرَأَةٍ مُسْلِمَةٍ أَعْتَقَتْ امْرَأَةً مُسْلِمَةً كَانَتْ فَكَاكَهَا مِنْ النَّارِ يُجْزِي كُلُّ عُضْوٍ مِنْهَا عُضْوًا مِنْهَا
