Sayyiduna Abu Sa'id (may Allah be pleased with him) narrates: When the Messenger of Allah (peace and blessings be upon him) was among us, we used to give sadaqat al-fitr (zakat al-fitr). On behalf of every young and old, slave and free person, we used to give the measure of one sa' of wheat, cheese (aqit), barley, dates or raisins.
