Is the gold that I took from my wife and the other financial sums considered a debt owed by the husband and his father, given that the husband claims the gold was a gift and not part of the Mahr?

The shabka (bridal gift) is the property of the wife, and she has the right to reclaim it if the husband borrowed it, unless she gifted it to him willingly. The husband must be warned against injustice and unlawfully consuming people's wealth. One can seek the help of someone whose word is heard. It is not permissible in a debt contract to stipulate a return of an increase on it; rather, it should be returned in kind. It is advisable to look at the positive aspects of married life to preserve the family.
