The wife’s consent is not a condition of taking her back after divorce
Question

                If a man divorces his wife in a fit of temper, then two weeks later he comes to take her back, but she does not agree to go back to him, because he is unjust and has a number of wives, and he does not treat them fairly and he had forsaken her for more than a year – does she become haraam for him and is she regarded as divorced, or what?.
Praise be to Allah.
    Firstly: 

    The divorce issued by one who is angry and does not know what 
    he is saying because of his anger or temper does not count as such. But if 
    his anger did not affect his reasoning, and he knew what he was saying, then 
    it does count as a divorce. The issue of divorce at times of anger has been 
    discussed in the answers to questions no.

    Secondly: 

    The husband has the right to take his wife back and it is not 
    essential that she agree to that, so long as he is taking her back within 
    the ‘iddah of a first or second talaaq, because Allaah says (interpretation 
    of the meaning): 

    “And divorced women shall wait (as regards their marriage) 
    for three menstrual periods, and it is not lawful for them to conceal what 
    Allaah has created in their wombs, if they believe in Allaah and the Last 
    Day. And their husbands have the better right to take them back in that 
    period, if they wish for reconciliation. And they (women) have rights (over 
    their husbands as regards living expenses) similar (to those of their 
    husbands) over them (as regards obedience and respect) to what is 
    reasonable, but men have a degree (of responsibility) over them. And Allaah 
    is All-Mighty, All-Wise”

    [al-Baqarah 2:228]

    This verse points to the conditions of taking back the wife, 
    which are: 

    1-That it applies to talaaq 
    (divorce). If it is the matter of annulment of the marriage, the husband 
    cannot take her back, because Allaah says “And divorced women”.
    

    2-That it should be a revocable 
    divorce, which can only be a first or second talaaq. The phrase “The 
    divorce is twice” [al-Baqarah 2:229] refers to the divorce where it is 
    possible to take back the wife. If the third talaaq takes place, then he 
    cannot take her back unless she marries another husband in a genuine 
    marriage, then he separates from her in a proper manner after consummating 
    the marriage.

    3-It should be within the ‘iddah 
    period, because Allaah says “And their husbands have the better right to 
    take them back in that period” i.e., during the ‘iddah. If the ‘iddah 
    comes to an end and he wants to take her back, that is only possible with a 
    new marriage contract and mahr.

    4-By taking her back, he should 
    not intend to harm her, rather he should intend to reconcile and set things 
    straight, because Allaah says “if they wish for reconciliation”. If 
    he intended to harm her, she has to prove that to the shar’i judge so that 
    he may rule as he sees fit.

    The verse clearly indicates that the wife has no choice in 
    the matter if the husband wants to take her back, and she has no right to 
    refuse to go back to him, because Allaah says “And their husbands have 
    the better right to take them back”. Even if she does not go back to his 
    house, if he says he takes her back and brings witnesses to that, then he 
    has in fact taken her back. 

    Thirdly: 

    The ‘iddah period during which the husband can take back the 
    wife is “three menstrual periods” i.e., three menstrual cycles 
    according to the majority of scholars, or before she gives birth, if she is 
    pregnant. 

    Based on this, what is mentioned in the question about him 
    wanting to take her back after two weeks is within the ‘iddah period, unless 
    she was pregnant and gave birth before he took her back. 

    Fourthly: 

    Divorce does not take place just by keeping away from one's 
    spouse and forsaking her. In the answer to question no. 11681 we have 
    explained that a lengthy absence on the husband’s part does not count as a 
    divorce unless a divorce is issued by the husband or qaadi. 

    Fifthly: 

    The husband who has several wives must fear Allaah with 
    regard to his wives and treat them fairly as enjoined by Allaah. For more 
    information on the obligation to treat co-wives fairly, see the answer to 
    question no. 10091 and
    13740. 

    Sixthly: 

    If a man forsakes his wife for no legitimate reason, that is 
    haraam. If he shuns her in order to set her straight and make her do some 
    duty that she has forsaken or give up some sin that she is doing, it is 
    permissible for him to forsake her. 

    Undoubtedly for a man to forsake his wife for such a long 
    time (a year) indicates that the problem is serious and that they cannot 
    solve it. In that case Allaah has enjoined appointing two arbitrators, one 
    from his family and the other from hers, to examine the matter and rule 
    according to whatever they think is in the interests of the couple and will 
    ward off harm from the one who is being harmed. 

    Allaah says (interpretation of the meaning): 

    “If you fear a breach between them twain (the man and his 
    wife), appoint (two) arbitrators, one from his family and the other from 
    hers; if they both wish for peace, Allaah will cause their reconciliation. 
    Indeed Allaah is Ever All‑Knower, Well‑Acquainted with all things”

    [al-Nisa’ 4:35]

    The husband should understand that he is enjoined to do one 
    of two things: 

    He should either keep his wife and treat her kindly, or he 
    should divorce her in a proper manner, giving her her rights and not 
    wronging her. Allaah says (interpretation of the meaning): 

    “after that, either you retain her on reasonable terms or 
    release her with kindness”

    [al-Baqarah 2:229].
