Aishah narrated that : the Prophet (ﷺ) 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."
