He who emancipates a slave, Allah will set free from Hell every limb (of his body) for every limb of his (slave's) body, even his private parts.  

عَنْ رَسُولِ اللَّهِ ﷺ قَالَ مَنْ أَعْتَقَ رَقَبَةً أَعْتَقَ اللَّهُ بِكُلِّ عُضْوٍ مِنْهَا عُضْوًا مِنْ أَعْضَائِهِ مِنَ النَّارِ حَتَّى فَرْجَهُ بِفَرْجِهِ

عَنْ رَسُولِ اللهِ ﷺ قَالَ مَنْ أَعْتَقَ رَقَبَةً أَعْتَقَ اللهُ ﷻ بِكُلِّ عُضْوٍ مِنْهَا عُضْوًا مِنْهُ مِنَ النَّارِ  

[Machine] The Messenger of Allah ﷺ said, "Whoever frees a slave, Allah will free from every limb of his body a limb from the Fire."  

قَالَ رَسُولُ اللَّهِ ﷺ «مَنْ أَعْتَقَ رَقَبَةً فَكَّ اللَّهُ بِكُلِّ عُضْوٍ مِنْ أَعْضَائِهِ عُضْوًا مِنْ أَعْضَائِهِ مِنَ النَّارِ»  

[Machine] The Prophet (PBUH) said: "Whoever frees a believing slave, Allah will free from Hellfire every limb of theirs, freeing one limb per limb of the slave they have freed."  

عَنِ النَّبِيِّ ﷺ قَالَ «مَنْ أَعْتَقَ رَقَبَةً مُؤْمِنَةً أَعْتَقَ اللَّهُ بِكُلِّ عُضْوٍ مِنْهَا عُضْوًا مِنْهُ مِنَ النَّارِ»

أَنَّ النَّبِيَّ ﷺ قَالَ «مَنْ أَعْتَقَ مُؤْمِنًا فِي الدُّنْيَا أَعْتَقَ اللهُ بِكُلِّ عُضْوٍ مِنْهُ عُضْوًا مِنَ النَّارِ»

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

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 أَعْتَقَ اللهُ بِكُلِّ عُضْوٍ مِنْهَا عُضْوًا مِنْهُ مِنَ النَّارِ»  

"أَعْتقوا عنه رقبةً يعتق الله بكل عضو مِنْها عضْوًا منْه مِنَ النَّارِ".  

"مَنْ أَعْتَقَ رَقَبَةً مُسْلِمَةً أَعَتَقَ اللهُ بِكُلِّ عُضْوٍ مِنْها عُضْوًا مِنْ أَعْضَائِهِ مِنَ النَّارِ، حَتَّى يَعْتِقَ فَرْجَهُ بَفَرْجِهِ".
