Riyad us Saliheen: Hadith 1534

Hind, the wife of Abu Sufyan, said to the Prophet (ﷺ): Abu Sufyan is a niggardly man and does not give me and my children adequate provisions for maintenance unless I take something from his possession without his knowledge. The Prophet (ﷺ) said to her, "Take from his possessions on a reasonable basis that much which may suffice for you and your children."
