Sayyidah Aishah (may Allah be pleased with her) said that the Messenger of Allah (peace and blessings be upon him) said: "When a woman feeds (others) from her husband's house without causing any ruin or harm, she will have her reward, her husband will have the same, and likewise the treasurer will have his reward for what he earned, and she has (reward) for what she spent."
