Narrated ‘Aishah (RA): Hind came to the Prophet (peace be upon him) and said: Messenger of Allah, Abu Sufyan is a stingy person. Is there any harm to me if I spend on his dependants from his property without his permission? The Prophet (peace be upon him) replied: There is no harm to you if you spend according to the custom.
Sunan Abi Dawud, Book 24, Hadith 118
