Then the Messenger of Allah ﷺ returned and they said, 'O Messenger of Allah, Ussayd is our imam, but he is sick and he prayed with us while seated.' The Messenger of Allah ﷺ said, 'Then pray behind him while seated, for the imam should be followed. When he prays while seated, then pray behind him while seated.' This hadith has a sound chain of narration and it has not been excluded from Sahih."  

أَنَّهُ كَانَ تَأَوَّهُ وَكَانَ يَؤُمُّنَا فَصَلَّى بِنَا قَاعِدًا فَعَادَهُ رَسُولُ اللَّهِ ﷺ فَقَالُوا يَا رَسُولَ اللَّهِ إِنَّ أُسَيْدًا إِمَامُنَا وَإِنَّهُ مَرِيضٌ وَإِنَّهُ صَلَّى بِنَا قَاعِدًا فَقَالَ رَسُولُ اللَّهِ ﷺ «فَصَلُّوا وَرَاءَهُ قُعُودًا فَإِنَّ الْإِمَامَ لِيُؤْتَمَّ بِهِ فَإِذَا صَلَّى قَاعِدًا فَصَلُّوا خَلْفَهُ قُعُودًا» صَحِيحُ الْإِسْنَادِ وَلَمْ يُخَرِّجَاهُ صحيح
