A woman is rewarded for giving from her home — even the family's food — without ruining it, with her husband's general consent. The Prophet ﷺ said: “When a woman gives from her household food, not causing ruin, she has its reward for what she gave, her husband for what he earned, and the keeper likewise — none diminishing the other.” (al-Bukhārī & Muslim).
العربية: عن عائشة رضي الله عنها أنّ النبيّ ﷺ قال: «إذا أنفقت المرأة من طعام بيتها غير مُفسِدة كان لها أجرها بما أنفقت، ولزوجها بما كسب، وللخازن مثلُ ذلك، لا ينقص بعضهم أجر بعض». (البخاري ومسلم).
Women too earn the reward of giving — from the home's food and means, harming nothing.
