Is it permissible for the husband to use the car that his wife sacrificed to purchase for traveling with his second wife, and is it fair to alternate using it for travel, knowing that the first wife lives far from her family? And is it permissible for him to take possessions from her house to use them in the second wife’s house, or to buy new provisions for her house without doing so for his first house, or to equalize the amount of food and fruit between two houses with different numbers of occupants, and is it permissible for him to bring his second wife into her house without her consent?

A woman's jealousy regarding polygyny is natural and she is not blamed for it, as long as it does not lead to injustice or transgression against her husband or co-wife. A righteous woman should be patient with this, seeking reward from Allah, and continue to treat her husband kindly.

The answer summarized the following nine points: 1. Justice between wives is a condition for the permissibility of polygyny, and it includes equality in obligatory spending. It is more cautious to ensure equality in additional spending. 2. The car is the husband's property, and there is no blame on him for using it to fulfill the needs of the second wife, even if the first wife helped in its purchase. 3. It is not just for the husband to condition the first wife's travel to her family on the second wife's sequential use of the car. 4. It is not forbidden for the husband to refrain from traveling by car with either of his wives. It is permissible for a wife to travel by public transportation with the presence of a mature, sane male guardian (mahram). 5. If the husband travels with one of his wives for her need, he must compensate the other wife for the missed days after his return. However, if he travels for his own need, he should draw lots between his wives, and he does not need to compensate the other after his return. 6. If the household appliances belong to the woman, the husband has no right to dispose of them except with her permission. If they belong to him, he may dispose of them provided it does not harm the first wife. 7. There is no blame on the husband for purchasing new appliances for his second home as long as there are similar ones in his first home. 8. The husband must be just in spending between his wives and also between his children, giving each family what is appropriate for it. 9. It is not permissible for the husband to bring one of his wives into the other's home if that would harm or anger the owner of the house.
