Muhammad bin al-Muthna - al-Zaman محمد بن المثنى أبو موسى - الزمن · The Book on Zakat

the Messenger of Allah sent a man from Banu Makhzun to collect charity, so he said to Abu Rafi: "Accompany me so that perhaps you may have some of it." So he said: "Not until I ask the Messenger of Allah." So he went to the Prophet to ask him, and he said: "Charity is not lawful for us, and to be the Mawda of a people to be the same as them."

the Prophet said: "When a woman gives in charity from her husband's house, she will get the reward for it, and for her husband is the same as that, and for the trustee is the same as that. The reward of each them will not be decreased at all by the reward of the other, for him is what he earned, and for her is what she spent."
