I heard the Prophet ﷺ talking at the pulpit while Al-Hasan was sitting beside him, and he (i.e. the Prophet ) was once looking at the people and at another time Al-Hasan, and saying, "This son of mine is a Saiyid (i.e. chief) and perhaps Allah will bring about an agreement between two sects of the Muslims through him."

سَمِعْتُ النَّبِيَّ ﷺ عَلَى الْمِنْبَرِ وَالْحَسَنُ إِلَى جَنْبِهِ يَنْظُرُ إِلَى النَّاسِ مَرَّةً وَإِلَيْهِ مَرَّةً وَيَقُولُ ابْنِي هَذَا سَيِّدٌ وَلَعَلَّ اللَّهَ أَنْ يُصْلِحَ بِهِ بَيْنَ فِئَتَيْنِ مِنَ الْمُسْلِمِينَ

That the Prophet ﷺ used to take him and Al-Hasan, and used to say, "O Allah! I love them, so please love them," or said something similar.

عَنِ النَّبِيِّ ﷺ أَنَّهُ كَانَ يَأْخُذُهُ وَالْحَسَنَ وَيَقُولُ اللَّهُمَّ إِنِّي أُحِبُّهُمَا فَأَحِبَّهُمَا أَوْ كَمَا قَالَ

The ˹severed˺ head of al-Ḥusayn was brought to ʿUbaydullāh b. Ziyād and was put in a tray, and then Ibn Ziyād started playing with a stick at the nose and mouth of al-Ḥusayn’s head and saying something about his handsome features. Anas then said ˹to him˺, "al-Ḥusayn resembled the Prophet ﷺ more than the others did." Anas added, "His hair was dyed with wasmah (a type of plant dye).

أُتِيَ عُبَيْدُ اللَّهِ بْنُ زِيَادٍ بِرَأْسِ الْحُسَيْنِ عَلَيْهِ السَّلاَمُ فَجُعِلَ فِي طَسْتٍ فَجَعَلَ يَنْكُتُ وَقَالَ فِي حُسْنِهِ شَيْئًا فَقَالَ أَنَسٌ:كَانَ أَشْبَهَهُمْ بِرَسُولِ اللَّهِ ﷺ وَكَانَ مَخْضُوبًا بِالْوَسْمَةِ

I saw the Prophet ﷺ carrying Al-Hasan on his shoulder an saying, "O Allah! I love him, so please love him."

رَأَيْتُ النَّبِيَّ ﷺ وَالْحَسَنُ عَلَى عَاتِقِهِ يَقُولُ اللَّهُمَّ إِنِّي أُحِبُّهُ فَأَحِبَّهُ

I saw Abu Bakr carrying Al-Hasan and saying, "Let my father be sacrificed for you; you resemble the Prophet and not ʿAli," while ʿAli was laughing at this.

رَأَيْتُ أَبَا بَكْرٍ ؓ وَحَمَلَ الْحَسَنَ وَهْوَ يَقُولُ بِأَبِي شَبِيهٌ بِالنَّبِيِّ لَيْسَ شَبِيهٌ بِعَلِيٍّ وَعَلِيٌّ يَضْحَكُ

Abu Bakr used to say, "Look after Muhammad ﷺ in (looking after) his family."

قَالَ أَبُو بَكْرٍ ارْقُبُوا مُحَمَّدًا ﷺ فِي أَهْلِ بَيْتِهِ

None resembled the Prophet ﷺ more than Al-Hasan bin ʿAli did.

لَمْ يَكُنْ أَحَدٌ أَشْبَهَ بِالنَّبِيِّ ﷺ مِنَ الْحَسَنِ بْنِ عَلِيٍّ

A person asked ʿAbdullah bin ʿUmar whether a Muslim could kill flies. I heard him saying (in reply). "The people of Iraq are asking about the killing of flies while they themselves murdered the son of the daughter of Messenger of Allah ﷺ . The Prophet ﷺ said, They (i.e. Hasan and Husain) are my two sweet basils in this world."

سَمِعْتُ عَبْدَ اللَّهِ بْنَ عُمَرَ وَسَأَلَهُ عَنِ الْمُحْرِمِ قَالَ شُعْبَةُ أَحْسِبُهُ يَقْتُلُ الذُّبَابَ فَقَالَ أَهْلُ الْعِرَاقِ يَسْأَلُونَ عَنِ الذُّبَابِ وَقَدْ قَتَلُوا ابْنَ ابْنَةِ رَسُولِ اللَّهِ ﷺ وَقَالَ النَّبِيُّ ﷺ هُمَا رَيْحَانَتَاىَ مِنَ الدُّنْيَا
