Is it obligatory for the questioner to divorce his wife - who is infertile and grieves over his inability to meet all her financial demands compared to her father's wealth - knowing that he loves her and does not want assistance from her father?

A daughter's marriage does not alter the ruling concerning the obligation of fairness between her and her siblings in gifts from the father. The wife has the right to demand justice from her father between her and her brother, unless there is a justifiable reason for preferring the brother. A wife should not be divorced merely because she is saddened by her desires not being met, for her remaining with her husband is better for her. We advise keeping the wife and not preventing her from accepting gifts from her father, and striving to have children through permissible means. If this is not possible, there is no harm in marrying another woman if one is confident in their ability to be just.
