Zakāt al-Fitr vs. Zakāt al-Mal
Muslims encounter two distinct obligations that share the word "zakāt," and confusing them is common. They differ in purpose, timing, amount, and who must pay.
Zakāt al-Mal, the zakāt of wealth
This is the annual obligation most people mean by "zakat." It is due on qualifying wealth, cash, savings, gold, business assets, certain investments, once that wealth has stayed above the niṣāb threshold for a full lunar year (the hawl). The rate is 2.5%. It is owed by any adult Muslim who meets the threshold, and the timing is personal: it falls on the anniversary of when your wealth first crossed niṣāb.
Zakāt al-Fitr, the zakāt of breaking the fast
This is a much smaller, fixed charity tied to Ramadan, due before the Eid al-Fitr prayer. Unlike zakat al-mal, it is owed on behalf of every member of a household, including children and dependents, by the head of the household, regardless of whether they meet the niṣāb. It is traditionally given as a measure of staple food (or its cash equivalent), and its purpose is to ensure even the poor can celebrate Eid.
Why the distinction matters
They are not interchangeable. Paying one does not discharge the other. Zakat al-mal is wealth-based and personal-timed; zakat al-fitr is head-count-based and calendar-fixed to the end of Ramadan. A household will often owe both in the same year.
