Q: Who should pay the Zakat al-fitrah of a guest who stays at the host’s home
only the night before the ‘Id al-Fitr?
A: Their fitrah does not rest with the host.
Q: If the guest pays his fitrah, does it exempt the host from paying it?
A: On assumption that the guest is a dependant of the host, then if he gives his
firtah with the permission of the host and on his behalf, the host will be
exempted from paying it.
Q: Should the person, who had a guest at the night before ‘Id al-Fitr and only
in the morning he understood that it was ‘Id al-Fitr, pay the fitrah of both
himself and the guest?
A: Not being aware of moon sighting has no effect on the rule of Zakat
al-fitrah. Anyhow, it is already mentioned that the fitrah of a one-night guest
rests with himself.
