That the Messenger of Allah ﷺ said: "Eat olive and use its oil, for indeed it is a blessed tree."  

قَالَ رَسُولُ اللَّهِ ﷺ كُلُوا الزَّيْتَ وَادَّهِنُوا بِهِ فَإِنَّهُ مِنْ شَجَرَةٍ مُبَارَكَةٍ  

Another chain from Zaid bin Aslam, from his father, from the Prophet ﷺ with similar. And he did not mention "from 'Umar" in it.  

عَنِ النَّبِيِّ ﷺ نَحْوَهُ وَلَمْ يَذْكُرْ فِيهِ عَنْ عُمَرَ  

"The Prophet ﷺ said: Eat of its oil and use it (the olives), for indeed it is from a blessed tree."  

حَدَّثَنَا أَبُو أَحْمَدَ الزُّبَيْرِيُّ وَأَبُو نُعَيْمٍ قَالاَ حَدَّثَنَا سُفْيَانُ عَنْ عَبْدِ اللَّهِ بْنِ عِيسَى عَنْ رَجُلٍ يُقَالُ لَهُ عَطَاءٌ مِنْ أَهْلِ الشَّامِ عَنْ أَبِي أَسِيدٍ قَالَ قَالَ النَّبِيُّ ﷺ كُلُوا الزَّيْتَ وَادَّهِنُوا بِهِ فَإِنَّهُ مِنْ شَجَرَةٍ مُبَارَكَةٍ
