The Messenger of Allah ﷺ while teaching us (the principles of faith), said: Do not try to go ahead of the Imam, recite takbir when he recites it, and when he says: "Nor of those who err" you should say Amin, bow down when he bows down, and when he says: "Allah listens to him who praises Him" say: "O Allah, our Lord, to Thee be the praise".  

كَانَ رَسُولُ اللَّهِ ﷺ يُعَلِّمُنَا يَقُولُ لاَ تُبَادِرُوا الإِمَامَ إِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا قَالَ وَلاَ الضَّالِّينَ فَقُولُوا آمِينَ وَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَقُولُوا اللَّهُمَّ رَبَّنَا لَكَ الْحَمْدُ  

“The Messenger of Allah ﷺ said: ‘The Imam has been appointed to be followed, so when he says Allahu Akbar, then say Allahu Akbar, when he recites, then listen attentively; when he says: Not (the way) of those who earned Your anger, nor of those who went astray,[1:7] then say Amin; when he bows then bow; when he says Sami’ Allahu liman hamidah (Allah hears those who praise Him), then say Allahumma Rabbana wa lakal-hamd (O Allah, our Lord, to You is the praise);” when he prostrates then prostrate; and if he prays sitting down then all of you pray sitting down.’”  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّمَا جُعِلَ الإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا قَرَأَ فَأَنْصِتُوا وَإِذَا قَالَ {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلاَ الضَّالِّينَ} فَقُولُوا آمِينَ وَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَقُولُوا اللَّهُمَّ رَبَّنَا وَلَكَ الْحَمْدُ وَإِذَا سَجَدَ فَاسْجُدُوا وَإِذَا صَلَّى جَالِسًا فَصَلُّوا جُلُوسًا أَجْمَعِينَ  

[Machine] The Messenger of Allah ﷺ taught us our prayers and Sunnahs, and he said, "Indeed, the imam is to be followed. So when he says 'Allahu Akbar,' say 'Allahu Akbar,' and when he says, 'not of those who have evoked [Your] anger or of those who are astray' [Al-Fatiha 7], say 'Ameen,' as Allah, the Most High, will answer your supplication. And when he bows, bow, and when he raises his head, raise yours, and when he says, 'Allah hears whoever praises Him,' say, 'Our Lord, to You is all praise,' as Allah hears you. And when he prostrates, prostrate, and when he raises his head, raise yours. Indeed, the imam prostrates before you and raises before you." The Messenger of Allah ﷺ said, "So do, as such is done."  

عَلَّمَنَا رَسُولُ اللهِ ﷺ صَلَاتَنَا وَسُنَّتَنَا فَقَالَ إِنَّمَا الْإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا قَالَ {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ} [الفاتحة 7] فَقُولُوا آمِينَ يُجِبْكُمُ اللهُ تَعَالَى وَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا رَفَعَ فَارْفَعُوا وَإِذَا قَالَ سَمِعَ اللهُ لِمَنْ حَمِدَهُ فَقُولُوا رَبَّنَا لَكَ الْحَمْدُ يَسْمَعِ اللهُ لَكُمْ وَإِذَا سَجَدَ فَاسْجُدُوا وَإِذَا رَفَعَ فَارْفَعُوا؛ فَإِنَّ الْإِمَامَيَسْجُدُ قَبْلَكُمْ وَيَرْفَعُ قَبْلَكُمْ قَالَ رَسُولُ اللهِ ﷺ فَتِلْكَ بِتِلْكَ  

[Machine] The Messenger of Allah ﷺ taught us our prayers and rituals and he said, "The Imam should be followed in prayer. So when he says Takbir, say Takbir, and when he recites the verse {Not the way of those who earned Your anger, nor of those who went astray} [Al-Fatiha 7], say Ameen, for Allah will answer your supplication. And when he bows, bow, and when he raises his head, raise yours. And when he says, 'Allah hears him who praises Him,' say, 'O Allah, our Lord, praise be to You.' Allah will hear your supplication. And when he prostrates, prostrate, and when he raises his head, raise yours. The Imam prostrates before you and raises his head before you." The Messenger of Allah ﷺ said, "This is for you."  

عَلَّمَنَا رَسُولُ اللهِ ﷺ صَلَاتَنَا وَسُنَّتَنَا فَقَالَ إِنَّمَا الْإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا قَالَ {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ} [الفاتحة 7] فَقُولُوا آمِينَ يُجِبْكُمُ اللهُ تَعَالَى وَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا رَفَعَ فَارْفَعُوا وَإِذَا قَالَ سَمِعَ اللهُ لِمَنْ حَمِدَهُ فَقُولُوا اللهُمَّ رَبَّنَا لَكَ الْحَمْدُ يَسْمَعِ اللهُ لَكُمْ وَإِذَا سَجَدَ فَاسْجُدُوا وَإِذَا رَفَعَ فَارْفَعُوا؛ فَإِنَّ الْإِمَامَ يَسْجُدُ قَبْلَكُمْ وَيَرْفَعُ قَبْلَكُمْ قَالَ رَسُولُ اللهِ ﷺ تِلْكَبِتِلْكَ  

[Machine] The Messenger of Allah ﷺ used to teach us not to rush the Imam in bowing, so when he says "Allahu Akbar", say "Allahu Akbar", and when he prostrates, prostrate. And when he says, "Not (the way) of those who have earned Your anger, nor of those who have gone astray," say "Ameen" because when the words of the angels coincide with this, then the sins of those who are in the mosque are forgiven. And when he says, "Allah listens to the one who praises Him," say "Our Lord, to You is the praise."  

كَانَ رَسُولُ اللهِ ﷺ يُعَلِّمُنَا أَنْ لَا تُبَادِرُوا الْإِمَامَ بِالرُّكُوعِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا سَجَدَ فَاسْجُدُوا وَإِذَا قَالَ {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ} [الفاتحة 7] فَقُولُوا آمِينَ فَإِنَّهُ إِذَا وَافَقَ كَلَامَ الْمَلَائِكَةِ غُفِرَ لِمَنْ فِي الْمَسْجِدِ وَإِذَا قَالَ سَمِعَ اللهُ لِمَنْ حَمِدَهُ فَقُولُوا رَبَّنَا لَكَ الْحَمْدُ  

[Machine] The Prophet ﷺ used to teach us not to preempt the Imam in bowing, and when he says "Allahu Akbar," say "Allahu Akbar," and when he says "not of those who have evoked [Your] anger or of those who are astray," say "Ameen." For when the words of the angels coincide with his words, the sins of those present in the mosque are forgiven. And when he prostrates, prostrate. And when he says "Allah hears whoever praises Him," say "Our Lord, and to You is the praise." And when he says "And when he prostrates," prostrate.  

كَانَ رَسُولُ اللهِ ﷺ يُعَلِّمُنَا أَنْ لَا تُبَادِرُوا الْإِمَامَ بِالرُّكُوعِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا قَالَ غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ فَقُولُوا آمِينَ فَإِنَّهُ إِذَا وَافَقَ كَلَامَ الْمَلَائِكَةِ غُفِرَ لِمَنْ فِي الْمَسْجِدِ وَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا قَالَ سَمِعَ اللهُ لِمَنْ حَمِدَهُ فَقُولُوا رَبَّنَا وَلَكَ الْحَمْدُ وَإِذَا سَجَدَ فَاسْجُدُوا  

"إِنَّما جعلَ الإِمامُ ليؤتَمَّ به، فإِذا كبَّر فكبِّروا، وإِذا قَرأ فأَنْصِتُوا، وإِذا قال، {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ}، فقُولوا: آمين، وإذا رَكَعَ فاركعوا، وإذا قال: سمع اللَّه لمن حَمِدَهُ فقولوا: اللَّهُمَّ ربّنا ولك الحمد، وإذا سَجَدَ فاسْجُدُوا. وإِذا صلى جالسًا فصَلُّوا جلوسًا".
