Sahih Muslim Book 18, Hadith Number 4251.

Chapter : Judgment is to be pronounced on evidence, and one who is eloquent in his plea (may win the case).

‘Aisha reported: Hind, the daughter of ‘Utba, wife of Abu Sufyan, came to Allah’s Messenger (may peace be upon him) 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 (may peace be upon him) said: Take from his property what is customary which may suffice you and your children.
