Hadith 11:74
Abu Hurairah (May Allah be pleased with him) reported:
The Messenger of Allah (ﷺ) said, "He who sets free a Muslim slave, Allah will deliver from the fire of Hell every limb of his body in return for every limb of the slave's body, even his private parts." [Al-Bukhari and Muslim] .
وعن أبي هريرة رضي الله عنه قال: قال لي رسول الله صلى الله عليه وسلم : "من أعتق رقبة مسلمة أعتق الله بكل عضو منه عضوًا منه من النار حتى فرجه بفرجه" ((متفق عليه))
