A Muslim who emancipates a Muslim (slave). Allah will save from Fire every limb of his for every limb (of the slave). Sa'id b. Marjana said: When I heard this hadith from Abu Huraira (Allah be pleased with him), I went away and made a mention of it to 'Ali b. Husain and he at once emancipated the slave for which Ibn ja'far was prepared to pay ten thousand dirhams or one thousand dinars. (Using translation from Muslim 1509d)
