Does a woman receive the reward for feeding a fasting person when she prepares the food, or must she be the one who provided the ingredients?

The reward for feeding a fasting person is not limited to those who spent their money, but also includes those who cooked and prepared the food. The man receives his reward for what he spent and strove for, and the woman receives her reward for what she did and toiled for. The treasurer or the one who delivered the food receives a similar reward; as the Prophet, peace and blessings be upon him, said: "When a woman spends from the food of her house, without causing any waste, she will have her reward for what she spent, and her husband will have his reward for what he earned, and the treasurer will have a similar reward. None of their rewards will be diminished in any way." Participating in an act of obedience means participating in its reward, even if the amount varies.
