Narrated 'Aisha: Allah's Apostle said, "When a woman gives in charity from her husband's meals without wasting the property of her husband, she will get a reward for it, and her husband too will get a reward for what he earned and the store-keeper will have the reward likewise."
— Sahih Bukhari, Volume 2, Book 24: Obligatory Charity Tax (Zakat), Hadith #518
