Volume 3, Book 46, Number 694:
Narrated Abu Dhar:
I asked the Prophet, “What is the best deed?” He replied, “To believe in Allah and to fight for His
Cause.” I then asked, “What is the best kind of manumission (of slaves)?” He replied, “The manumis –
sion of the most expensive slave and the most beloved by his master.” I said, “If I cannot afford to do
that?” He said, “Help the weak or do good for a person who cannot work for himself.” I said, “If I can –
not do that?” He said, “Refrain from harming others for this will be regarded as a charitable deed for
your own good.”
