Alms Tax: The Death of the Owner of the Produce

Practical Laws of Islam as per the teachings of Ayatullah Sistani

Ruling 1882

If the owner of some wheat, barley, dates, or grapes dies after zakat on them has become obligatory, the zakat on them must be given from his estate. However, if he dies before zakat on them becomes obligatory, each of the heirs whose share reaches the niṣāb must give zakat on their share.
