Another chain from Zaid bin Aslam, from his father, from the Prophet (ﷺ) with similar. And he did not mention "from 'Umar" in it.
Jami` at-Tirmidhi Book 25, Hadith 68
← Previous Hadith That the Messenger of Allah (ﷺ) said: "Eat olive and use its oil, for indeed it is a blessed tree."

We do not know of this Hadith except through the narration of 'Abdur-Razzaq from Ma'mar (narrators in the chain of this Hadith). 'Abdur-Razzaq would narrate this with Idtirab. Sometimes he mentioned in it: "From 'Umar, from the Prophet (ﷺ)" and sometimes he reported it indicating doubt, saying: "I think it is from 'Umar from the Prophet (ﷺ)." And sometimes he said: "From Zaid bin Aslam, from his father, from the Prophet (ﷺ)" in a Mursal form.

Jami` at-Tirmidhi Book 25, Hadith 67 Next Hadith → "The Prophet (ﷺ) said: Eat of its oil and use it (the olives), for indeed it is from a blessed tree."

This Hadith is Gharib from this route. We only know of it from the narration of Sufyan At-Thawri, from 'Abdullah bin 'Eisa.
