[Machine] Narrated by the Prophet, ﷺ : "Indeed, the imam was appointed to be followed, so do not differ with him. When he says Allah is the Greatest, then say Allah is the Greatest. When he recites, then listen attentively. When he says 'not of those who have gone astray or those who have incurred wrath', then say 'Ameen'. When he bows, then bow. When he says 'Allah listens to the one who praises him', then say 'O Allah, our Lord, to You is the praise'. When he prostrates, then prostrate. And when he prays while sitting, then all pray sitting altogether. And this is the way it is."  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّمَا جُعِلَ الْإِمَامُ لِيُؤْتَمَّ بِهِ فَلَا تَخْتَلِفُوا عَلَيْهِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا قَرَأَ فَأَنْصِتُوا وَإِذَا قَالَ غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ فَقُولُوا آمِينَ وَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا قَالَ سَمِعَ اللهُ لِمَنْ حَمِدَهُ فَقُولُوا اللهُمَّ رَبَّنَا لَكَ الْحَمْدُ وَإِذَا سَجَدَ فَاسْجُدُوا وَإِذَا صَلَّى جَالِسًا فَصَلُّوا جُلُوسًا أَجْمَعُونَ وَكَذَلِكَ
