"The Messenger of Allah ﷺ said: 'The Imam is appointed to be followed, so when he says the takbir, say the takbir, and when he recites, be silent, and when he says: "Sami' Allahu liman hamidah (Allah hears those who praise Him)," say: "Allahumma rabbana lakal-hamd (Our Lord, to You be praise)."  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّمَا جُعِلَ الإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا قَرَأَ فَأَنْصِتُوا وَإِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَقُولُوا اللَّهُمَّ رَبَّنَا لَكَ الْحَمْدُ  

"The Messenger of Allah ﷺ said: 'The Imam is appointed to be followed, so when he says the takbir, say the takbir, and when he recites, be silent.'"  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّمَا الإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا قَرَأَ فَأَنْصِتُوا قَالَ أَبُو عَبْدِ الرَّحْمَنِ كَانَ الْمُخَرِّمِيُّ يَقُولُ هُوَ ثِقَةٌ يَعْنِي مُحَمَّدَ بْنَ سَعْدٍ الأَنْصَارِيَّ  

The Prophet ﷺ said: The imam is appointed only to be followed. This version adds: When he recites (the Qur'an), keep silent."  

عَنِ النَّبِيِّ ﷺ قَالَ إِنَّمَا جُعِلَ الإِمَامُ لِيُؤْتَمَّ بِهِ بِهَذَا الْخَبَرِ زَادَ وَإِذَا قَرَأَ فَأَنْصِتُوا  

"The Messenger of Allah ﷺ said: 'The Imam is appointed to be followed, so when he says the takbir, say the takbir, and when he recites, be silent, and when he says: "Sami' Allahu liman hamidah (Allah hears those who praise Him)," say: "Allahumma rabbana lakal-hamd (Our Lord, to You be praise)." (Using translation from Nasāʾī 921)  

قَالَ رَسُولُ اللهِ ﷺ إِنَّمَا جُعِلَ الْإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا قَرَأَ فَأَنْصِتُوا وَإِذَا قَالَ سَمِعَ اللهُ لِمَنْ حَمِدَهُ فَقُولُوا اللهُمَّ رَبَّنَا لَكَ الْحَمْدُ  

"إِنَّمَا جُعِلَ الإِمام لِيُؤْتَمَّ به، فإذا كبَّرَ فكبِّروا، وإِذَا قَرَأَ فأَنْصِتُوا وإِذا قال: سمِع اللَّه لمن حمد فقولوا: ربَّنَا لك الحمدُ ".  

"إِنَّما جُعِلَ الإِمامُ ليؤتَمَّ به، فإِذا كبَّر فكبِّروا، وإِذَا قرَأَ فأَنْصِتُوا".
