Encyclopedia of Prophetic Hadiths

The Messenger of Allah (may Allah's peace and blessings be upon him) enjoined Zakat al-Fitr as one Sā‘ of dates or one Sā‘ of barley on the slave and the free person, the male and the female, the young and the old from among the Muslims. He ordered that it be given before the people go out to the prayer.

When the Messenger of Allah (may Allah's peace and blessings be upon him) was among us, we used to give out Zakat al-Fitr on behalf of every young and old person, free or slave, as one Sā‘ of food, or one Sā‘ of Aqit (dried yogurt), or one Sā‘ of barley, or one Sā‘ of dates, or one Sā‘ of raisins. We continued giving it out until Mu‘āwiyah ibn Abi Sufyān (may Allah be pleased with him) came to us for Hajj or ‘Umrah. He addressed the people from the pulpit, and among the things he said to the people was: Verily, I see that two Mudds of the Syrian wheat are equivalent to one Sā‘ of dates. So, people started applying this. Abu Sa‘īd said: As for me, I will continue to give it as I used to give it for as long as I live.
