When Banu Quraizah capitulated agreeing to accept Sa’d’s judgement, the Prophet ﷺ sent a messenger to him. When he came riding on a white ass, the prophet ﷺ said: stand up to (show respect to) your chief, or he said : “to the best of you”. He came and sat beside the Messenger of Allah (May peace be upon him).  

أَنَّ أَهْلَ قُرَيْظَةَ لَمَّا نَزَلُوا عَلَى حُكْمِ سَعْدٍ أَرْسَلَ إِلَيْهِ النَّبِيُّ ﷺ فَجَاءَ عَلَى حِمَارٍ أَقْمَرَ فَقَالَ النَّبِيُّ ﷺ قُومُوا إِلَى سَيِّدِكُمْ أَوْ إِلَى خَيْرِكُمْ فَجَاءَ حَتَّى قَعَدَ إِلَى رَسُولِ اللَّهِ ﷺ  

when he came near the mosque, he said to the Ansar; stand up showing respect to your chief.  

لِلأَنْصَارِ قُومُوا إِلَى سَيِّدِكُمْ  

I never saw anyone more like the Messenger of Allah ﷺ in respect of gravity, calm deportment, pleasant disposition - according to al-Hasan's version: in respect of talk and speech. Al-Hasan did not mention gravity, calm deportment, pleasant disposition - than Fatimah, may Allah honour her face. When she came to visit him (the Prophet) he got up to (welcome) her, took her by the hand, kissed her and made her sit where he was sitting; and when he went to visit her, she got up to (welcome) him, took him by the hand, kissed him, and made him sit where she was sitting.  

عَنْ أُمِّ الْمُؤْمِنِينَ عَائِشَةَ ؓ أَنَّهَا قَالَتْ مَا رَأَيْتُ أَحَدًا كَانَ أَشْبَهَ سَمْتًا وَهَدْيًا وَدَلاًّ وَقَالَ الْحَسَنُ حَدِيثًا وَكَلاَمًا وَلَمْ يَذْكُرِ الْحَسَنُ السَّمْتَ وَالْهَدْىَ وَالدَّلَّ بِرَسُولِ اللَّهِ ﷺ مِنْ فَاطِمَةَ كَرَّمَ اللَّهُ وَجْهَهَا كَانَتْ إِذَا دَخَلَتْ عَلَيْهِ قَامَ إِلَيْهَا فَأَخَذَ بِيَدِهَا وَقَبَّلَهَا وَأَجْلَسَهَا فِي مَجْلِسِهِ وَكَانَ إِذَا دَخَلَ عَلَيْهَا قَامَتْ إِلَيْهِ فَأَخَذَتْ بِيَدِهِ فَقَبَّلَتْهُ وَأَجْلَسَتْهُ فِي مَجْلِسِهَا
