Sayyiduna Abu Hurayrah (may Allah be pleased with him) says: "Sadaqat al-fitr is obligatory upon every free person and slave, male and female, young and old, poor and rich: a sa' of dates or half a sa' of wheat."
Ata' (may Allah have mercy on him) says that the one who receives sadaqat al-fitr should also pay it on his own behalf. Al-Hasan, Abu al-Aliyah and al-Sha'bi (may Allah have mercy on them) also said the same.
