Sahih Bukhari Volume 009, Book 089, Hadith Number 275.
Narrated By 'Aisha : Hind bint 'Utba bin Rabia came and said. "O Allah's Apostle! By Allah, there was no family on the surface of the earth, I like to see in degradation more than I did your family, but today there is no family on the surface of the earth whom I like to see honored more than yours." Hind added, "Abu Sufyan is a miser. Is it sinful of me to feed our children from his property?" The Prophet said, "There is no blame on you if you feed them (thereof) in a just and reasonable manner.
