I receive gifts, mostly eatables such as chocolates, from my aunt who does not pay Khums. Will it have any affect on my inner soul directly or indirectly if I eat them?
You are not responsible for the Khums of the gifts received by you. You can eat the eatables. If it remains with you for a full year unused fully or partly, you will be responsible to pay the Khums of the remaining after full year if anything remains unused.
Wassalam.
