Bulugh al-Maram #745

A’ishah (RAA) narrated that The Messenger of Allah (ﷺ) said: “When a woman gives some of the foodstuff (which she has in her house) in charity without being extravagant (without being wasteful), she will receive the reward for what she has spent, and her husband will receive the reward because of his earning, and the keeper (if any) will be similarly rewarded. The reward of one will not decrease the reward of the others.” Agreed upon.
