The Messenger of Allah ﷺ said, "When a woman spends from the food of her household without causing waste, she earns her reward for what she has spent, her husband earns his reward for what he has earned, and the storekeeper earns a similar reward. None of them diminishes the reward of the others in the slightest."
قال رسول الله ﷺ: إذا أنفقت المرأة من طعام بيتها غير مفسدة كان لها أجرها بما أنفقت، ولزوجها أجرم بما كسب، وللخازن مثل ذلك لا ينقص بعضهم أجر بعض شيئا.
Bukhari narrated it in the Book of Zakat (1425), and Muslim in the Book of Zakat (1024), both from the hadith of Jareer, from Mansur, from Shaqiq, from Masruq, from Ayesha, and I have mentioned it. In another version, "from her husband's food."As for what was narrated from Saad, who said that when the Messenger of Allah ﷺ took the pledge from the women, a dignified woman stood up, as if she were one of the women of Mudar, and said, "O Prophet of Allah, we are a burden on our fathers and our sons" (Abu Dawud said, and I believe it also mentions "and our husbands") "so what is permissible for us from their wealth?" He said, "Fresh dates, you may eat them and give them as gifts."This is munqati (a hadith with a broken chain). Abu Dawud narrated it (1686) from Muhammad bin Sawwar Masri, who said, Abdul-Salam bin Harb narrated to us, from Yunus bin Ubayd, from Ziyad bin Jubayr bin Hayyah, from Saad, who said, and then he mentioned it. Hakim graded it sahih (4/134) according to the standard of the two Shaykhs (Bukhari and Muslim).I say, it is as he said, except that there is a break between Ziyad bin Jubayr and Saad bin Abu Waqqas. Abu Hatim and Abu Zura said that his narration from Saad bin Abu Waqqas is mursal. See Marasil Ibn Abu Hatim (page 61), and Jami Tahsil (177).
