He told his wife to make food for him during the day in Ramadan!
Question

                I have a daughter who is married and she and her husband came to stay with us during the month of Ramadan. After we had fasted for one week of the month, my daughter's husband went with his friends for an excursion, and the shaytaan tempted them and they ate and drank during the day in Ramadan. On the morning of the next day, my daughter's husband asked her to make food for him but she refused. He swore that he would divorce her if she did not make it, and she swore that she would not make it. In order to get out of this situation, I asked my son's wife to make food for him and she refused, but I forced her to do it, so she made food for him reluctantly, and he sat and ate on his own and none of us ate with him. Were we sinning in this case? What do we have to do in order to expiate this sin?.
Praise be to Allah.
      There is no doubt that breaking the fast in Ramadan with no 
      legitimate excuse is a major sin and grave evil. If it is done because of 
      an excuse such as travelling -- which means a journey of approximately 70 
      or 80 km, which is the distance that could be covered in one night on 
      mounts and on foot, which is what is called travelling -- there is nothing 
      wrong with breaking the fast in this case. But if one is at home or on the 
      outskirts of the city, that is not called travelling and breaking the fast 
      in this case is a major sin. The one who helps the person to break his 
      fast shares with him in the sin, because Allah, may He be glorified, says 
      (interpretation of the meaning):

    “Help you one another in Al‑Birr and At‑Taqwa (virtue, 
    righteousness and piety); but do not help one another in sin and 
    transgression”

    [al-Maa’idah 5:2].

    The one who helps a person who breaks the fast in Ramadan 
    without an excuse, by offering him food or coffee or tea or any other food 
    or drink is a sinner who is a partner in sin with the one who breaks the 
    fast, but his fast is still valid and is not invalidated by his helping that 
    person. But he is a sinner and he has to repent to Allah. 

    As you forced your daughter or your son's wife to make the 
    food, you have to repent to Allah. You did wrong by telling her to make food 
    for him. She did right by not obeying him, because there is no obedience to 
    a created being if it involves disobedience towards the Creator. The Prophet 
    (blessings and peace of Allah be upon him) said: “Obedience is only in that 
    which is right and proper.” If her husband ordered her to bring him food 
    during the day in Ramadan, without any excuse that would make it permissible 
    for him to break the fast, such as sickness or travelling, she has no right 
    to help him to do that which Allah has forbidden, even if he gets angry or 
    divorces her, because obedience to Allah takes precedence over obedience to 
    one's husband or father or ruler, because the Messenger (blessings and peace 
    of Allah be upon him) said: “Obedience is only in that which is right and 
    proper”; he also said: “There is no obedience to any created being if it 
    involves disobedience towards Allah.” 

    This man is not regarded as a traveller because he stayed 
    with them for a week and it seems that he had decided to stay for more than 
    four days. This means that he was obliged to fast according to the correct 
    scholarly view, which is the view of the majority of scholars. As they had 
    decided to stay for more than four days with their in-laws, they should have 
    fasted with them. If the stay is four days or less, they are not obliged to 
    fast because they are travellers, but if they do fast, there is nothing 
    wrong with that. But as they intended to stay with them for more than four 
    days, what they should have done in this case is fast, so as to avoid an 
    area of scholarly disagreement and so as to follow the view of the majority, 
    because the basic principle is that one should fast in Ramadan, and there is 
    some doubt as to whether it was permissible to break the fast. End quote.
