Narrated by Sayyidah Aisha (may Allah be pleased with her): The Prophet (peace and blessings of Allah be upon him) said: If a woman spends something from her husband's wealth and her intention is not to waste her husband's property, then she will get the reward for spending, and the husband will also get the reward because he earned it, and the treasurer is also included in this ruling. One person's reward does not diminish the reward of the other.
