Sunan Ibn Majah 2294

It was narrated from 'Aishah that the Messenger of Allah (ﷺ) said:"When a woman spends" and my father said: - "When a woman feeds (the poor) from her husband's house, without spending too much, she will have her reward, and he will be rewarded likewise because he earned it , and she will be rewarded for what she spent. The same applies to the storekeeper, without anything being detracted from their rewards.”
