حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ عَنْ الزُّهْرِيِّ عَنْ أَنَسِ بْنِ مَالِکٍ أَنَّ النَّبِيَّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ صُرِعَ عَنْ فَرَسٍ فَجُحِشَ شِقُّهُ الْأَيْمَنُ فَدَخَلْنَا نَعُودُهُ وَحَضَرَتْ الصَّلَاةُ فَصَلَّی بِنَا قَاعِدًا وَصَلَّيْنَا وَرَائَهُ قُعُودًا فَلَمَّا قَضَی الصَّلَاةَ قَالَ إِنَّمَا جُعِلَ الْإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا کَبَّرَ فَکَبِّرُوا وَإِذَا رَکَعَ فَارْکَعُوا وَإِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَقُولُوا رَبَّنَا وَلَکَ الْحَمْدُ وَإِذَا سَجَدَ فَاسْجُدُوا وَإِذَا صَلَّی قَاعِدًا فَصَلُّوا قُعُودًا أَجْمَعِينَ
ابن ماجہ · Hadith 1238
It was narrated from Anas bin Malik that the Prophet SAW fell from his horse and he suffered some lacerations on his right side. We went to visit him and the time for prayer came, He led us in prayer sitting down, and we prayed behind him sitting down. When he finished the prayer he said: "The Imam is appointed to be followed. When he says Allahu Akbar, then say Allahu Akbar; when he bows, then bow; when he says Sami' Allahu liman hamidah, then say Rabbana wa lakal-hamd; when he prostrates then prostrate; and if he prays sitting down then pray sitting down."(Sahih).
