Charity was the voluntary act of giving assistance to people in need, without any expectation of personal gain.
In 2371, Rom embezzled money from the Ferengi Benevolent Association, a charitable organization set up by the Prophet-influenced Grand Nagus Zek, of which he was the Senior Administrator. After a restored Zek folded the charity, Rom revealed his actions to his brother Quark, who was impressed, and noted that their father Keldar would have been, too. (DS9: "Prophet Motive")
