Take a loan from an orphan''s money

A: The money that your sister has given you from the orphans' funds should be returned to them, and you should try hard to estimate the amount in order to fulfill your duty. However, if the money is from your adult sister's share, you are not obliged to return it, and there is no harm in eating from the food served to you. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
