Narrated Abu Bakra:
حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ ، حَدَّثَنَا يَحْيَى بْنُ آدَمَ ، حَدَّثَنَا حُسَيْنٌ الْجُعْفِيُّ ، عَنْ أَبِي مُوسَى ، عَنِ الْحَسَنِ ، عَنْ أَبِي بَكْرَةَ ـ رضى الله عنه ـ أَخْرَجَ النَّبِيُّ صلى الله عليه وسلم ذَاتَ يَوْمٍ الْحَسَنَ فَصَعِدَ بِهِ عَلَى الْمِنْبَرِ، فَقَالَ " ابْنِي هَذَا سَيِّدٌ، وَلَعَلَّ اللَّهَ أَنْ يُصْلِحَ بِهِ بَيْنَ فِئَتَيْنِ مِنَ الْمُسْلِمِينَ " .
Once the Prophet (ﷺ) brought out Al-Hasan and took him up the pulpit along with him and said, "This son of mine is a Saiyid (i.e. chief) and I hope that Allah will help him bring about reconciliation between two Muslim groups."
