Narrated 'Aishah: Hind, the mother of Mu'awiyah, came to the Messenger of Allah (ﷺ) and said: 'Abu Sufyan is a stingy person. He does not give me as much (money) as suffices me and my children. Is there any harm to me if I take something from his property ? He said: Take as much as suffices you and your children according to the custom.
