The Merit of Emancipation of Slaves

Imam Al-Nawawi’s Riyad-us-Saliheen
Chapter 236
The Merit of Emancipation of Slaves

Allah, the Exalted, says:

But he has not attempted to pass on the path that is steep (i.e., the path which will lead to goodness and success). And what will make you know the path that is steep? (It is) freeing a neck (slave).” (90:11-13)

1358.  Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (sallallaahu ’alayhi wa sallam) 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].

1359.  Abu Dharr (May Allah be pleased with him) reported: I asked the Messenger of Allah (sallallaahu ’alayhi wa sallam), “Which deed is most excellent?” He replied, “Faith in Allah and Jihad in His path.” I then asked, “Which slaves are most excellent (to set free)?” He replied, “Those who are held in high esteem by their people and whose value is higher.”
[Al-Bukhari and Muslim].
