Is it permissible to live with a husband who takes out a riba-based loan?
Question

                Is it sinful for a wife to live with a husband who takes out loan to start a business? Can this be a ground for divorce?  I would be grateful if you could advice me in how to convience him that it is wrong what he is doing.
Praise be to Allah.
    If the loan that he has asked for is halaal, i.e. it is not 
    based on riba, and he intends to pay it back, then there is nothing wrong 
    with this, and this is not regarded as a sinful loan. 

    But if this loan is a riba-based loan, then it is haraam and 
    it is not permissible for him to take it or to start a business with this 
    haraam money. 

    “And whosoever fears Allaah and keeps his duty to Him, He 
    will make a way for him to get out (from every difficulty).

     And He will provide him from (sources) he never could 
    imagine”

    [al-Talaaq 65:2-3]

    and :

    “Whoever gives up something for the sake of Allaah, Allaah 
    will compensate him with something better than that.” 

    If you want to advise him, then in Question no. 
    9054 you will 
    find some comments on this topic which you can give him so that he might 
    benefit from that, and avoid that which is haraam.  

    With regard to his consuming riba, this may be grounds for 
    you to ask him for a divorce (talaaq) or to ask for khula’, but you do not 
    have to do that, rather it is o.k. for you to stay with him and live with 
    him whilst continuing to advise him to do that which is better, especially 
    if there is the hope that he will mend his ways. 

    With regard to eating from his money, if he has a permissible 
    source of income other than this, then there is no sin on you or on you 
    children if you eat from this money. But if all his earnings are haraam and 
    you cannot find any other source of maintenance, and you have no other 
    halaal source of income, then it is permissible for you to take just what 
    you need, and no more, because Allaah says (interpretation of the meaning): 

    “So keep your duty to Allaah and fear Him as much as you 
    can”

    [al-Taghaabun 64:16]

    So in this case if you take money, you are taking what he is 
    obliged to spend on you. But you should still continue to advise him and 
    tell him to refrain from taking haraam loans, and to look for a way that is 
    acceptable according to sharee’ah, so that he can do work and earn his 
    provision thereby. 

    And Allaah is the Source of strength.
