According to the narration of the grandson of Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) (who narrates through his father from his grandfather), Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrates: "I saw some men of the Arabs come to the Messenger of Allah (peace and blessings be upon him) and say: 'O Messenger of Allah! We are people who own livestock, and we pay its zakah; will that suffice on our behalf for the zakah of Ramadan (Sadaqat al-Fitr)?' The Messenger of Allah (peace and blessings be upon him) said: 'No. Pay it on behalf of the young and the old, the free and the slave, for it is a means of purification for you.'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Rubayh bin Abd al-Rahman except Kathir bin Abdullah al-Muzani."
