Narrated Anas:

that the Messenger of Allah ﷺ used to go out to his Companions from The Muhajirin and the Ansar while they were sitting, and Abu Bakr and 'Umar would be with them. No one would lift their sight towards him except Abu Bakr and 'Umar, because they used to look at him, and he would look at them, and they would smile at him, and he would smile at them.

حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا أَبُو دَاوُدَ، حَدَّثَنَا الْحَكَمُ بْنُ عَطِيَّةَ، عَنْ ثَابِتٍ، عَنْ أَنَسٍ، أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَخْرُجُ عَلَى أَصْحَابِهِ مِنَ الْمُهَاجِرِينَ وَالأَنْصَارِ وَهُمْ جُلُوسٌ فِيهِمْ أَبُو بَكْرٍ وَعُمَرُ فَلاَ يَرْفَعُ إِلَيْهِ أَحَدٌ مِنْهُمْ بَصَرَهُ إِلاَّ أَبُو بَكْرٍ وَعُمَرُ فَإِنَّهُمَا كَانَا يَنْظُرَانِ إِلَيْهِ وَيَنْظُرُ إِلَيْهِمَا وَيَتَبَسَّمَانِ إِلَيْهِ وَيَتَبَسَّمُ إِلَيْهِمَا .

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ غَرِيبٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ الْحَكَمِ بْنِ عَطِيَّةَ . وَقَدْ تَكَلَّمَ بَعْضُهُمْ فِي الْحَكَمِ بْنِ عَطِيَّةَ .
