Alms Tax: Change of Dependency Before Sunset
Practical Laws of Islam as per the teachings of Ayatullah Sistani
Ruling 2015
If a person is a dependant of someone and before sunset he becomes a dependant of someone else, his fiṭrah becomes obligatory for the person he became a dependant of. For example, if a girl moves to her husband’s house before sunset, her husband must give her fiṭrah.
