Abu Dawud

A woman should not spend from her husband’s house without his permission.

Abu Umamah al-Bahili radi Allahu anhu narrates that the Messenger of Allah sallallahu alayhi wa sallam said:
«لا تنفق امرأة شيئا من بيت زوجها إلا بإذن زوجها قيل: يا رسول الله ولا الطعام؟ قال ذاك افضل اموالنا»
“A woman should not spend anything from her husband’s house without his permission.” It was asked, “O Messenger of Allah, not even grain?” He replied, “That is among our best wealth.”
Takhrij: (Abu Dawud (3565), Tirmidhi (670), Ibn Majah (2398), Musnad Ahmad 5/267, Musnad Tayalisi (1127), Al-Musannaf by Abd al-Razzaq (16621), Al-Tamhid 1/230, Bayhaqi 4/193-194, Sharh al-Sunnah 6/204)

It is understood from this that if a woman cannot spend in charity or alms something of lesser value than grain without her husband’s permission, then how could she spend grain, which is among the best of wealth? [تحفة الاحوذي 3/288]

If a woman knows that her husband does not object to her giving charity and alms, but rather likes it, then there is no harm in her spending.

It is narrated from Aisha radi Allahu anha that the Messenger of Allah sallallahu alayhi wa sallam said:
«اذا تصدقت المراة من بيت زوجها كان لها به اجر وللزوج مثل ذلك وللخازن مثل ذلك ولا ينقص كل واحد منهم من اجر صاحبه شيئا بما كست ولها بما انفقت»
“When a woman gives charity from her husband’s house, she will have its reward, and the husband will have a reward similar to it, and the treasurer will also have a reward like it, and each will not diminish the reward of the other. The man has the reward for earning, and the woman has the reward for spending.” [ترمذي 671 نسائي كبري 2/35]

In another narration from Aisha radi Allahu anha, it is stated that the Messenger of Allah sallallahu alayhi wa sallam said:
“When a woman gives a gift from her husband’s house happily, and she is not extravagant in giving, she will have a reward like that of her husband, and for the woman is what she intended with a good intention, and the treasurer will also have a reward like it.” [ترمذي 672 نسائي كبري 5/379]

Allamah Mubarakpuri rahimahullah writes in his commentary:
«وهذا محمول على اذن الزوج لها بذلك صريحا او دلالة» [تحفة الاحوذي 3/390]
“This is based on the woman having her husband’s permission, whether that permission is explicit or implicit.”
The meaning is that the man has clearly given the woman permission to spend, or it is known from his actions that he is not displeased with her spending.

In Mirqat Sharh Mishkat 4/435, it is also stated that this matter is in accordance with the custom of the people of Hijaz. Their custom was that they had given their wives and servants permission to show hospitality to guests, and to feed and give drink to the needy, the poor, and neighbors. The Messenger of Allah sallallahu alayhi wa sallam encouraged his ummah towards this good custom and excellent trait.

Therefore, when a woman has permission from her husband, whether this permission is explicit or in some other form, she should spend. Like the man, the woman will also receive reward: the man for earning, and the woman for spending. In our homes, it is known from the habits of the men, and the women continue to spend in the way of Allah in donations and charity, and the husbands are not displeased with this. In any case, the woman should obtain the husband’s permission and approval. «والله اعلم بالصواب»
