أَخْبَرَنَا قُتَيْبَةُ عَنْ مَالِکٍ عَنْ ابْنِ شِهَابٍ عَنْ أَنَسِ بْنِ مَالِکٍ أَنَّ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ رَکِبَ فَرَسًا فَصُرِعَ عَنْهُ فَجُحِشَ شِقُّهُ الْأَيْمَنُ فَصَلَّی صَلَاةً مِنْ الصَّلَوَاتِ وَهُوَ قَاعِدٌ فَصَلَّيْنَا وَرَائَهُ قُعُودًا فَلَمَّا انْصَرَفَ قَالَ إِنَّمَا جُعِلَ الْإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا صَلَّی قَائِمًا فَصَلُّوا قِيَامًا وَإِذَا رَکَعَ فَارْکَعُوا وَإِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَقُولُوا رَبَّنَا لَکَ الْحَمْدُ وَإِذَا صَلَّی جَالِسًا فَصَلُّوا جُلُوسًا أَجْمَعُونَ
سنن نسائی · Hadith 836
It was narrated from Anas bin Malik that the Messenger of Allah صلی اللہ علیہ وآلہ وسلم rode a horse and fell from it, and sustained an injury on his right side. He led one of the prayers sitting, and we prayed behind him sitting. When he had finished he said: “The Imam is appointed to be followed. If he prays standing then pray standing; when he bows, bow; when he says, Sami’ Allahu liman Hamidah (Allah hears those who praise Him), say ‘Rabbanalakal hamd (Our Lord, to You be praise); and if he prays sitting then pray sitting, all of you.” (Sahih).
