I said to Ka'b bin Murrah, tell us a Hadith from the Messenger of Allah ﷺ, but be careful. He said: I heard the Messenger of Allah ﷺ say: “Whoever frees a Muslim man, he will be his ransom from the Fire; each of his bones will suffice (as a ransom) for each of his bones. Whoever frees two Muslim women, they will be his ransom from the Fire; each of their two bones will suffice (as a ransom) for each of his bones.”  

حَدِّثْنَا عَنْ رَسُولِ اللَّهِ ﷺ وَاحْذَرْ قَالَ سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ أَعْتَقَ امْرَأً مُسْلِمًا كَانَ فِكَاكَهُ مِنَ النَّارِ يُجْزِئُ بِكُلِّ عَظْمٍ مِنْهُ عَظْمٌ مِنْهُ وَمَنْ أَعْتَقَ امْرَأَتَيْنِ مُسْلِمَتَيْنِ كَانَتَا فِكَاكَهُ مِنَ النَّارِ يُجْزِئُ بِكُلِّ عَظْمَيْنِ مِنْهُمَا عَظْمٌ مِنْهُ  

“I said: 'O Messenger of Allah ﷺ, which slave is best?' He said: ‘The one who is most precious to his master and most valuable in price.' ”  

قُلْتُ يَا رَسُولَ اللَّهِ أَىُّ الرِّقَابِ أَفْضَلُ قَالَ أَنْفَسُهَا عِنْدَ أَهْلِهَا وَأَغْلاَهَا ثَمَنًا
