On the authority of Zayd ibn Aslam, from his father, that ʿUmar ibn al-Khaṭṭāb said: The Messenger of Allah (peace and blessings be upon him) said: "Eat olive oil and anoint yourselves with it, for it comes from a blessed tree." (1)

This is a ḥadīth that we do not know except from the narration of ʿAbd al-Razzāq, and ʿAbd al-Razzāq used to be inconsistent in his transmission of this ḥadīth. Sometimes he would mention in it "on the authority of ʿUmar, from the Prophet (peace and blessings be upon him)," and sometimes he would narrate it with doubt, saying: "I think it is on the authority of ʿUmar, from the Prophet (peace and blessings be upon him)," and sometimes he would say: "on the authority of Zayd ibn Aslam, from his father, from the Prophet (peace and blessings be upon him)" as a mursal (incomplete chain).

1957 – Abū Dāwūd Sulaymān ibn Maʿbad narrated to us, he said: ʿAbd al-Razzāq narrated to us, from Maʿmar, from Zayd ibn Aslam, from his father, from the Prophet (peace and blessings be upon him), similar to it, and he did not mention in it "on the authority of ʿUmar." (2)

1958 – Maḥmūd ibn Ghaylān narrated to us, he said: Abū Aḥmad al-Zubayrī and Abū Nuʿaym narrated to us, they said: Sufyān narrated to us, from ʿAbd Allāh ibn ʿĪsā, from a man called ʿAṭāʾ, from the people of Syria, from Abū Usayd, who said: The Prophet (peace and blessings be upon him) said: "Eat from olive oil and anoint yourselves with it, for it is a blessed tree."

--------------------------------------------
(1) Ḥasan (good) due to corroborating evidence; this chain's narrators are trustworthy, except that it is declared defective due to being mursal (discontinuous chain). It is corroborated by the ḥadīth of Abū Usayd that follows. It was also narrated by Ibn Mājah (3319). It is found in "Sharḥ Mushkil al-Āthār" by al-Ṭaḥāwī (4450). See also what follows it, no. (1958).

(2) The mursal narration was transmitted by ʿAbd al-Razzāq in his "Muṣannaf" (19568).

(3) Its chain is weak due to the unknown status of ʿAṭāʾ al-Shāmī, while the rest of its narrators are trustworthy. It serves as corroborating evidence =
