Sahih Bukhari Volume 003, Book 043, Hadith Number 640.
Narated By 'Aisha : Hind bint 'Utba (Abu Sufyan's wife) came and said, "O Allah's Apostle! Abu Sufyan is a miser. Is there any harm if I spend something from his property for our children?" He said, there is no harm for you if you feed them from it justly and reasonably (with no extravagance)."
