From Sahih Muslim (Hadith 2364):
A'isha reported Allah's Messenger (ﷺ) as saying:When a woman gives in charity some of the food in her house, without causing any damage, there is reward for her for whatever she has given, and a reward for her husband for what he earned. The same applies to the trustee. In no respect does the one diminish the reward of the other
