Sesungguhnya imam dijadikan untuk diikuti, apabila dia rukuk maka rukuklah, bila dia mengangkat kepalanya maka angkatlah kepala
Imam Abu Dawud : 509حَدَّثَنَا الْقَعْنَبِيُّ عَنْ مَالِكٍ عَنْ ابْنِ شِهَابٍ عَنْ أَنَسِ بْنِ مَالِكٍأَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَكِبَ فَرَسًا فَصُرِعَ عَنْهُ فَجُحِشَ شِقُّهُ الْأَيْمَنُ فَصَلَّى صَلَاةً مِنْ الصَّلَوَاتِ وَهُوَ قَاعِدٌ وَصَلَّيْنَا وَرَاءَهُ قُعُودًا فَلَمَّا انْصَرَفَ قَالَ إِنَّمَا جُعِلَ الْإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا صَلَّى قَائِمًا فَصَلُّوا قِيَامًا وَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا رَفَعَ فَارْفَعُوا وَإِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَقُولُوا رَبَّنَا وَلَكَ الْحَمْدُ وَإِذَا صَلَّى جَالِسًا فَصَلُّوا جُلُوسًا أَجْمَعُونَ
Narrated to us [Al-Qa'nabi] from [Malik] from [Ibnu Syihab] from [Anas bin Malik], that Rasulullah shallallahu 'alaihi wasallam rode a horse and fell, injuring his right side. He performed an obligatory prayer sitting, and we prayed behind him sitting. After finishing, he said, 'The imam is appointed to be followed. If he prays standing, pray standing. If he bows, bow. If he rises, rise. If he says, "Sami'allaahu liman hamidah" (Allah hears those who praise Him), say, "Rabbanaa Walakal Hamdu" (Our Lord, to You be praise). If he prays sitting, all of you pray sitting.'
