I heard Messenger of Allah ﷺ as saying: He who emancipates a believing slave. Allah will set free from Fire his every limb for every limb of his (slave's), even his private parts for his. (Using translation from Muslim 1509c)  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَنْ أَعْتَقَ رَقَبَةً مُؤْمِنَةً أَعْتَقَ اللهُ بِكُلِّ عُضْوٍ مِنْهُ عُضْوًا مِنَ النَّارِ حَتَّى يُعْتِقَ فَرْجَهُ بِفَرْجِهِ»  

If anyone emancipates a Muslim slave, Allah will set free from Hell an organ of his body for every organ of his (slave's) body. (Using translation from Muslim 1509a)   

قَالَ رَسُولُ اللهِ ﷺ «مَنْ أَعْتَقَ رَقَبَةً مُؤْمِنَةً أَعْتَقَ اللهُ بِكُلِّ إِرْبٍ مِنْهَا إِرْبًا مِنْهُ مِنَ النَّارِ» حَتَّى إِنَّ اللهَ لَيَعْتِقُ بِالْيَدِ الْيَدَ وَبِالْفَرْجِ الْفَرْجَ  

[Machine] On the authority of the Prophet ﷺ , he said: "Whoever among Muslims frees a Muslim, his reward for freeing him will be that for every limb of the freed person, a limb of him will be freed from Hellfire."  

عَنِ النَّبِيِّ ﷺ قَالَ «أَيُّمَا امْرِئٍ مُسْلِمٍ أَعْتَقَ امْرَأً مُسْلِمًا كَانَ فِكَاكَهُ مِنَ النَّارِ يُجْزِئُ كُلُّ عُضْوٍ مِنْهُ عُضْوًا مِنْهُ»  

[Machine] The Messenger of Allah ﷺ said, "Whoever frees a slave and Allah protects him with every organ from the organs of the slave, a part of him will be protected from the fire."  

قَالَ رَسُولُ اللهِ ﷺ «مَنْ أَعْتَقَ نَسَمَةً وَقَاهُ اللهُ بِكُلِّ عُضْوٍ مِنْهَا عُضْوًا مِنْهُ مِنَ النَّارِ»  

[Machine] To his sons, Abdullah, Bilal, and others: "O my sons, shall I not tell you a hadith that my father narrated to me from the Messenger of Allah ﷺ?" They said, "Yes." He said, "Whoever frees a slave, Allah will free from Hellfire for every limb of the slave, a limb from the Fire."  

لِبَنِيهِ عَبْدِ اللهِ وَبِلَالٍ وَغَيْرِهِمْ يَا بَنِيَّ أَلَا أُحَدِّثُكُمْ حَدِيثًا حَدَّثَنِيهِ أَبِي عَنْ رَسُولِ اللهِ ﷺ؟ قَالُوا بَلَى قَالَ «مَنْ يَعْنِي أَعْتَقَ رَقَبَةً أَعْتَقَ اللهُ مَكَانَ كُلِّ عُضْوٍ مِنْهُ عُضْوًا مِنَ النَّارِ»  

[Machine] I heard the Messenger of Allah (May ﷺ ) say, "Whoever frees a Muslim slave, Allah will make every bone from his bones a bone from the fire. And whoever emancipates a female Muslim slave, Allah will make every bone from her bones a bone from the fire."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «أَيُّمَا رَجُلٍ أَعْتَقَ رَجُلًا مُسْلِمًا فَإِنَّ اللهَ يَجْعَلُ وِقَاءَ كُلِّ عَظْمٍ مِنْ عِظَامِهِ عَظْمًا مِنْ عِظَامِ مُحَرَّرَهُ مِنَ النَّارِ وَأَيُّمَا امْرَأَةٍ مَسْلَمَةٍ أَعْتَقَتِ امْرَأَةً مَسْلَمَةً فَإِنَّ اللهَ جَاعِلٌ وِقَاءَ كُلِّ عَظْمٍ مِنْ عِظَامِهَا عَظْمًا مِنْ عَظْمِ مُحَرَّرِهَا مِنَ النَّارِ»  

[Machine] I asked the Messenger of Allah, ﷺ , which night is the most heard (by Allah)? He replied, "The last third of the night." He also used to say, "Whoever frees a Muslim slave, his freedom from the Fire will be to free each limb of the slave with a limb (of his own body), and whoever frees a Muslim woman slave, his freedom from the Fire will be to free each limb of her with a limb (of his own body)."  

سَأَلْتُ رَسُولَ اللهِ ﷺ أَيُّ اللَّيْلِ أَسْمَعُ؟ قَالَ «جَوْفُ اللَّيْلِ الْآخِرِ» قَالَ وَكَانَ يَقُولُ «أَيُّمَا امْرِئٍ مُسْلِمٍ أَعْتَقَ امْرَأً مُسْلِمًا فَهُوَ فِكَاكُهُ مِنَ النَّارِ يُجْزِئُ كُلُّ عَظْمٍ مِنْهُ عَظْمًا وَأَيُّمَا امْرَأَةٍ مَسْلَمَةٍ أَعْتَقَتِ امْرَأَةً مَسْلَمَةً فَهُوَ فِكَاكُهَا مِنَ النَّارِ كُلُّ عَظْمٍ مِنْهَا عَظْمٌ مِنْهَا»  

[Machine] The Prophet ﷺ said, "Whoever frees a Muslim slave, it will be his ransom from the Hellfire, limb by limb. And whoever frees two Muslim slave women, it will be his ransom from the Hellfire, two limbs by two limbs. And whoever frees a Muslim woman, it will be her ransom from the Hellfire, limb by limb."  

أَنَّ النَّبِيَّ ﷺ قَالَ «أَيُّمَا امْرِئٍ مُسْلِمٍ أَعْتَقَ امْرَأً مُسْلِمًا فَهُوَ فِكَاكُهُ مِنَ النَّارِ عَظْمٌ بِعَظْمٍ وَأَيُّمَا امْرِئٍ مُسْلِمٍ أَعْتَقَ امْرَأَتَيْنِ مُسْلِمَتَيْنِ فَهُوَ فِكَاكُهُ مِنَ النَّارِ عَظْمَتَيْنِ مِنْهَا بِعَظْمٍ وَأَيُّمَا امْرَأَةٍ مَسْلَمَةٍ أَعْتَقَتِ امْرَأَةً مَسْلَمَةً فَهِيَ فِكَاكُهَا مِنَ النَّارِ عَظْمٌ بِعَظْمٍ»  

[Machine] Narrated by the Prophet ﷺ , "Whoever emancipates a slave, his emancipation shall be his redemption from the Fire."  

عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ أَعْتَقَ رَقَبَةً فَهُوَ فِدَاؤُهُ مِنَ النَّارِ»  

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.” (Using translation from Ibn Mājah 2522)  

حَدِّثْنَا عَنْ رَسُولِ اللهِ ﷺ وَاحْذَرْ قَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَنْ أَعْتَقَ امْرَأً مُسْلِمًا كَانَ فِكَاكَهُ مِنَ النَّارِ يُجْزِئُ كُلُّ عَظْمٍ مَكَانَ عَظْمٍ مِنْهُ وَمَنْ أَعْتَقَ امْرَأَتَيْنِ مُسْلِمَتَيْنِ كَانَتَا فِكَاكَهُ مِنَ النَّارِ يَجْزِئُ مَكَانَ كُلِّ عَظْمَيْنِ مِنْهُمَا عَظْمٌ مِنْهُ»  

I heard the Messenger of Allah ﷺ say: If anyone emancipates a Muslim slave, that will be his ransom from Jahannam. (Using translation from Abū Dāʾūd 3966)   

حَدِّثْنَا حَدِيثًا سَمِعْتَهُ مِنْ رَسُولِ اللهِ ﷺ قَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَنْ أَعْتَقَ رَقَبَةً مَسْلَمَةً كَانَ فِدَاءُ كُلِّ عُضْوٍ مِنْهُ عُضْوًا مِنْهُ مِنْ نَارِ جَهَنَّمَ»
