Sahih al-Bukhari, Hadith 2209 ⓘ
Narrated Ibn `Umar: I was with the Prophet while he was eating fresh dates. He said, "From the trees there is a tree which resembles a faithful believer." I wanted to say that it was the date palm, but I was the youngest among them (so I kept quiet). He added, "It is the date palm."
حَدَّثَنَا أَبُو الْوَلِيدِ، هِشَامُ بْنُ عَبْدِ الْمَلِكِ حَدَّثَنَا أَبُو عَوَانَةَ، عَنْ أَبِي بِشْرٍ، عَنْ مُجَاهِدٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ كُنْتُ عِنْدَ النَّبِيِّ صلى الله عليه وسلم وَهْوَ يَأْكُلُ جُمَّارًا، فَقَالَ " مِنَ الشَّجَرِ شَجَرَةٌ كَالرَّجُلِ الْمُؤْمِنِ ". فَأَرَدْتُ أَنْ أَقُولَ هِيَ النَّخْلَةُ. فَإِذَا أَنَا أَحْدَثُهُمْ قَالَ " هِيَ النَّخْلَةُ ".
