عَنْ أَبِي هُرَيْرَةَ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ أَعْتَقَ رَقَبَةً مُسْلِمَةً أَعْتَقَ اللَّهُ بِكُلِّ عُضْوٍ مِنْهُ عُضْوًا مِنَ النَّارِ حَتَّى فَرْجَهُ بِفَرْجِهِ»
The Messenger of Allah (sallallahu alayhi wa sallam) said:, “If anyone emancipates a Muslim slave, God will set free from hell a member of the body for every member of his, even his private parts for his.”
