32 - Chapter: The Obligation of the Zakat of Ramadan upon the Young

2502 - Qutaybah informed us, saying: Malik narrated to us, from Nafi‘, from Ibn ‘Umar, who said: The Messenger of Allah, peace and blessings be upon him, made the Zakat of Ramadan obligatory upon every young and old, free and slave, male and female: a sa‘ of dates or a sa‘ of barley.

33 - Chapter: The Obligation of the Zakat of Ramadan upon the Muslims, Not upon Those with Whom a Treaty Has Been Made

2503 - Muhammad ibn Salamah and al-Harith ibn Miskin informed us — the latter by reading to him while I was listening, and the wording is his — from Ibn al-Qasim, who said: Malik narrated to me, from Nafi‘, from Ibn ‘Umar, that the Messenger of Allah, peace and blessings be upon him, made the Zakat of Fitr of Ramadan obligatory upon the people: a sa‘ of dates or a sa‘ of barley, upon every free person or slave, male or female, from among the Muslims.

============================================
And it has preceded before this via the chain of ‘Abd al-Warith ibn Sa‘id, from Ayyub al-Sakhtiyani, with it.

(1) Its chain of transmission is authentic. It is in "Al-Sunan al-Kubra" under number (2293).
Muslim also narrated it (984): (12) from Qutaybah ibn Sa‘id with this chain, and he paired with him ‘Abdullah ibn Maslamah ibn Qa‘nab and Yahya ibn Yahya, and he related the wording of Yahya, in which there is no statement "young and old," and in it there is the addition "from among the Muslims," and this wording will come in the two hadiths after it.
Ibn ‘Abd al-Barr said in "Al-Tamhid" 14/320: Thus Qutaybah narrated this hadith from Malik, not saying in it "from among the Muslims" ... and the preserved version from Malik includes "from among the Muslims." Al-Daraqutni also mentioned in "Al-‘Ilal" 6/342 that Qutaybah's statement "from among the Muslims" was dropped. See also "Al-Tamhid" 14/312.
And consider the two hadiths preceding it, and the hadiths following it.

(2) In (M): from ‘Abdullah ibn ‘Umar.
(3) In (R): and slave.
(4) In (H): or female.
(5) Its chain of transmission is authentic. Ibn al-Qasim: he is ‘Abd al-Rahman al-Misri the jurist, the companion of Imam Malik.
