The Prophet ﷺ said, "When a woman gives in charity from her husband's household, she earns a reward for it, and her husband receives a similar reward, and the storekeeper receives the same. None of them diminishes the reward of the others in the slightest. The husband is rewarded for what he earned, and she is rewarded for what she spent."

عن النبي ﷺ أنه قال إذا تصدقت المرأة من بيت زوجها كان لها به أجر وللزوج مثل ذلك وللخازن مثل ذلك ولا ينقص كل واحد منهم من أجر صاحبه شيئا له بما كسب ولها بما أنفقت
