Jami` at-Tirmidhi Book 25, Hadith 69
"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.
Another chain from Zaid bin Aslam, from his father, from the Prophet (ﷺ) with similar. And he did not mention "from 'Umar" in it.
From his father that Abu Hurairah informed them that the Prophet (ﷺ) said: "When the servant of one of you has endured heat and smoke preparing his food for him, then let him take him by the hand and make him sit him down with him. If he refuses, then let him take a morsel and feed him with it."
This Hadith is Hasan Sahih. Abu Khalid is the father of Isma'il, his name is Sa'd.
