‘A’isha reported God’s messenger as saying, “When a woman gives some of the food in her house, not wasting it, she will have her reward for what she has given and her husband will have his for what he earned. The same applies to a storekeeper. In no respect does the one diminish the reward of the other.” (Bukhari and Muslim.)
