The Permanent Committee for Scholarly Research and Ifta has clarified the key differences between Zakat al-Mal (zakat on wealth) and Zakat al-Fitr (zakat at the end of Ramadan).

First, the basis of the obligation differs. Zakat al-Mal is connected to specific types of productive wealth, such as money, gold, silver, livestock, and trade goods. It becomes obligatory when this wealth reaches a minimum threshold known as the 'nisab' and has been held for a full lunar year (the 'hawl'). In contrast, Zakat al-Fitr is connected to the individual person. It is obligatory upon every Muslim—male or female, young or old—who has enough food for themselves and their dependents for one day and one night, beyond their basic needs.

Second, the amount and type of payment are different. For Zakat al-Mal, the amount is typically a fixed percentage (e.g., 2.5% of monetary wealth). It is paid from the wealth itself, whether in cash or from the specific assets. For Zakat al-Fitr, the amount is fixed at one sa' (a unit of measure equivalent to approximately 2.5–3 kg) of a local staple food, such as dates, barley, rice, or flour. It is not calculated based on a person's total wealth.

Third, the timing of the obligation is distinct. Zakat al-Mal is due once a year after the 'hawl' is completed, and it can be paid whenever that date occurs for an individual. Zakat al-Fitr has a very specific window of time for its payment: it is due at the end of Ramadan and must be paid before the Eid al-Fitr prayer. It is permissible to pay it one or two days before Eid.

The wisdom behind each also differs. The primary purpose of Zakat al-Mal is to purify a person's wealth and to provide for the eight categories of recipients mentioned in the Qur'an. Zakat al-Fitr, as described in the hadith, serves as a purification for the fasting person from any idle or indecent speech during Ramadan and as a provision of food for the needy on the day of Eid.
