Where to pay zakaat al-fitr

I am a young man living in Kuwait, but I have taken my daughter to
America for medical treatment and I fasted Ramadaan in America. Do I
have to pay zakaat al-fitrin America or can I delegate my family in
Kuwait to pay it on my behalf? What is the ruling on paying zakaat
al-fitr in cash? Please note that in America they pay it in cash
instead of giving staple food.
Praise be to Allaah.
The scholars (may Allaah be pleased with them) stated that zakaat
al-fitr isconnected to numbers of people, not money, and it is to be
paid in the place where a person is on the night before Eid.
Ibn Qudaamah said in al-Mughni (4/134):
As for zakaat al-fitr, it is tobe paid in the land where the person
from whom it is due is present, whether his wealth is there or not.
End quote.
As for paying zakaat al-fitrin cash, we have explained in the answer
to question no. 22888 that it must be given in the form of food, and
thatpaying it in cash is not acceptable.
So you must try to give it in the form of food. If the poor person
refuses the food and asks for cash, then there is nothing wrong with
your giving it as cash in that case, because of need or necessity.
And Allaah knows best.
