(2) CHAPTER. It is obligatory to spend for one's wife and household.
Narrated Abu Huraira: The Prophet said, 'The best alms is that which is given when one is rich, and a giving hand is better than a taking one, and you should start first to support your dependents.' A wife says, 'You should either provide me with food or divorce me.' A slave says, 'Give me food and enjoy my service. A son says, Give me food; to whom do you leave me? The people said, O Abu Huraira! Did you hear that from Allah's Apostle ? He said, No, it is from my own self.
