Alms Tax: Delaying the Payment of Fitrah

Practical Laws of Islam as per the teachings of Ayatullah Sistani

Ruling 2040

If a person does not give fiṭrah until the time of ẓuhr prayers on the day Eid al-Fiṭr and does not set it aside either, then based on obligatory precaution, he must give fiṭrah afterwards without making the intention of giving it within its prescribed time (adāʾ) or belatedly (qaḍāʾ).
