It is narrated from Aishah (may Allah be pleased with her) that Hind said to the Prophet (peace and blessings be upon him): Abu Sufyan is a miserly man; is there any sin on me if I take something from his wealth? He (peace and blessings be upon him) said: "Take what is sufficient for you and your children, according to what is customary."
Imam Bukhari recorded it in his Sahih from Muhammad bin Kathir.
