It was narrated that 'Aishah said: "Hind came to the Messenger of Allah (ﷺ) and said : 'O Messenger of Allah, Abu Sufyan is a stingy man who does not spend enough on my child and I. Can I take from his wealth without him realizing?' He said: 'Take what is sufficient for you and your child on a reasonable basis.'"
