He does not work and his wife is spending on him – is this considered to be a debt that he owes?
Question

                If the is not working and the wife works and uses her money to pay the rent,buys food, and pay's all the other bills in the house does the husband owe the wive the money she spent if it was not agreed that it was sadaqah?
Praise be to Allah.We
      put this question to Shaykh ‘Abd-Allaah ibn Jibreen, may Allaah preserve
      him, who answered as follows:
      
 If
      there was no prior agreement, this is considered to be a gift and a
      donation, so she does not have the right to ask for it back at the time
      when she spent this money of her own accord. But if there was a prior
      condition that the money should be repaid, then Muslims are bound by their
      conditions and she has the right to ask, when the husband can afford it,
      for all that she has spent on his house and children.
      
 And
      Allaah knows best.
