Mukhtasar Muslim (Abridged) 891 — Virtue of freeing a believing slave

Abu Huraira (may Allah be pleased with him) reports that I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: Whoever frees a Muslim slave, Allah will free every limb of his in exchange for every limb of the slave from Hell, even his private part in exchange for the slave’s private part.
