From Sahih Muslim (Hadith 4477):
A'isha reported:Hind. the daughter of 'Utba, wife of Abu Sufyan, came to Allah's Messenger (ﷺ) and said: Abu Sufyan is a miserly person. He does not give adequate maintenance for me and my children, but (I am constrained) to take from his wealth (some part of it) without his knowledge. Is there any sin for me? Thereupon Allah's Messenger (ﷺ) said: Take from his property what is customary which may suffice you and your children
