Should the mother be compensated for her mortgaged gold, the price of which was used for the household, and is the household considered indebted to her for that?

If you took gold from your mother as a loan or borrowed it to pawn it, you must return an equal amount of gold. It is permissible to repay its value in cash at its market price on the due date. However, if your mother gave you the gold to pawn it as her agent, and the household members paid off the debt, then nothing is required of you. In fact, it seems she has no right to demand it from you. We advise you to be gentle with your mother and treat her kindly.
