Alms Tax: Paying Fitrah for a Guest Arriving After Sunset or for Iftar
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 2008
The fiṭrah of a guest who arrives at one’s house after sunset on the eve of Eid al-Fiṭr is, based on precaution, obligatory for the host provided that the guest is considered the host’s dependant; otherwise, it is not. If a person is invited to break his fast (ifṭār) on the eve of Eid al-Fiṭr, he is not considered the host’s dependant and the guest’s fiṭrah is not the responsibility of the owner of the house.
