What did Prophet Muhammad (saw) say about a husband and wife donating food from their home without causing any damage?
 'A'isha reported Allah's Messenger (may peace be upon him) 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.
