What should I do about my brothers' refusal to return my papers and my wife's jewelry that she left with them after I reconciled with my wife?

The brothers are not entitled to deny the wife's jewelry and the husband's papers deposited with them, as denying a trust is one of the major sins. Nor is it permissible for them to give the husband the choice between taking his right and cutting ties with them, for both are legitimate rights. The husband must be gentle with his brothers and mend the relationship, and while taking his right, he must not cut ties with them and should treat them kindly even if they treat him poorly.
