Narrated Abdullah ibn Maslamah ibn Qa'nab and Qutaybah ibn Sa'id: They said: Malik narrated to us. (Another chain:) Yahya ibn Yahya narrated to us—and the wording is his—he said: I read before Malik, from Nafi', from Ibn Umar, that the Messenger of Allah, peace and blessings be upon him, enjoined the Zakat al-Fitr of Ramadan upon the people: one sa' of dates or one sa' of barley, upon every free person or slave, male or female, among the Muslims.
