The Messenger of Allah ﷺ said to al-Hasan ibn Ali. This son of mine is a Sayyid (chief), and I hope Allah may reconcile two parties of my community by means of him. Hammad's version has: And perhaps Allah may reconcile two large parties of Muslims by means of him. (Using translation from Abū Dāʾūd 4662)   

قَالَ رَسُولُ اللَّهِ ﷺ لِلْحَسَنِ بْنِ عَلِيٍّ «إِنَّ ابْنِي هَذَا سَيِّدٌ وَلَعَلَّ اللَّهَ أَنْ يُصْلِحَ بِهِ بَيْنَ فِئَتَيْنِ مِنَ الْمُسْلِمِينَ عَظِيمَتَيْنِ»  

[Machine] "I saw the Messenger of Allah ﷺ with Al-Hasan ibn Ali while he was saying, 'Verily, this son of mine is a leader, and Allah will bring peace and reconciliation through him between two great factions of the Muslims.'"  

رَأَيْتُ رَسُولَ اللهِ ﷺ وَمَعَهُ الْحَسَنُ بْنُ عَلِيٍّ ؓ وَهُوَ يَقُولُ «إِنَّ ابْنِي هَذَا سَيِّدٌ وَإِنَّ اللهَ سَيُصْلِحُ عَلَى يَدَيْهِ بَيْنَ فِئَتَيْنِ مِنَ الْمُسْلِمِينَ عَظِيمَتَيْنِ»  

[Machine] The Messenger of Allah ﷺ said to Al-Hasan ibn Ali, "Indeed, my son is a master and I hope that Allah will use him to reconcile between two factions of my ummah."  

قَالَ رَسُولُ اللهِ ﷺ لِلْحَسَنِ بْنِ عَلِيٍّ ؓ «إِنَّ» ابْنِي هَذَا سَيِّدٌ وَإِنِّي أَرْجُو أَنْ يُصْلِحَ اللهُ بِهِ بَيْنَ فِئَتَيْنِ مِنْ أُمَّتِي  

[Machine] The Messenger of Allah, ﷺ , said to Hassan ibn Ali, "Verily, my son here is a leader, and I hope that Allah will reconcile through him between two groups of my Ummah."  

قَالَ رَسُولُ اللهِ ﷺ لِلْحَسَنِ بْنِ عَلِيٍّ ؓماُ «إِنَّ» ابْنِي هَذَا سَيِّدٌ وَإِنِّي لَأَرْجُو أَنْ يُصْلِحَ اللهُ بِهِ بَيْنَ فِئَتَيْنِ مِنْ أُمَّتِي
