Sahih Bukhari Volume 008, Book 078, Hadith Number 636.

Narated By 'Aisha : Hind bint 'Utba bin Rabi 'a said, "O Allah 's Apostle! (Before I embraced Islam), there was no family on the surface of the earth, I wish to have degraded more than I did your family. But today there is no family whom I wish to have honored more than I did yours." Allah's Apostle said, "I thought similarly, by Him in Whose Hand Muhammad's soul is!" Hind said, "O Allah's Apostle! (My husband) Abu Sufyan is a miser. Is it sinful of me to feed my children from his property?" The Prophet said, "No, unless you take it for your needs what is just and reasonable."
