ahmad:24396Aswad > Ḥammād b. Zayd > Hishām from his father > ʿĀʾishah

[Machine] When the Prophet ﷺ fell ill, his companions entered to visit him. They were trying to heal him, so he signaled to them to sit down. When he finished his prayer, the imam instructed them to follow his actions. When he said the takbir, they should say it as well. When he performed the ruku', they should also bow down. When he prayed while sitting, they should pray while sitting. And when he prayed while standing, they should pray while standing.  

أحمد:٢٤٣٩٦حَدَّثَنَا أَسْوَدُ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ عَنْ هِشَامٍ عَنْ أَبِيهِ عَنْ عَائِشَةَ قَالَتْ

لَمَّا مَرِضَ النَّبِيُّ ﷺ دَخَلَ عَلَيْهِ أَصْحَابُهُ يَعُودُونَهُ فَقَامُوا فَأَوْمَأَ إِلَيْهِمْ أَنِ اقْعُدُوا فَلَمَّا قَضَى صَلَاتَهُ قَالَ الْإِمَامُ يُؤْتَمُّ بِهِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا صَلَّى قَاعِدًا فَصَلُّوا قُعُودًا وَإِذَا صَلَّى قَائِمًا فَصَلُّوا قِيَامًا

The Imam is appointed to be followed. So recite takbir when he recites it, and bow down when he bows down and when he utters:" Allah listens to him who praises Him," say" O Allah, our Lord, for Thee be the praise." And when he prays, standing, you should pray standing. And when he prays sitting, all of you should pray sitting.  

مسلم:٤١٧حَدَّثَنِي أَبُو الطَّاهِرِ حَدَّثَنَا ابْنُ وَهْبٍ عَنْ حَيْوَةَ أَنَّ أَبَا يُونُسَ مَوْلَى أَبِي هُرَيْرَةَ حَدَّثَهُ قَالَ سَمِعْتُ أَبَا هُرَيْرَةَ يَقُولُ

عَنْ رَسُولِ اللَّهِ ﷺ أَنَّهُ قَالَ إِنَّمَا جُعِلَ الإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَقُولُوا اللَّهُمَّ رَبَّنَا لَكَ الْحَمْدُ وَإِذَا صَلَّى قَائِمًا فَصَلُّوا قِيَامًا وَإِذَا صَلَّى قَاعِدًا فَصَلُّوا قُعُودًا أَجْمَعُونَ

“The Messenger of Allah ﷺ 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; if he prays standing, then pray standing, and if he prays sitting down then pray sitting down.”

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّمَا جُعِلَ الإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَقُولُوا رَبَّنَا وَلَكَ الْحَمْدُ وَإِنْ صَلَّى قَائِمًا فَصَلُّوا قِيَامًا وَإِنْ صَلَّى قَاعِدًا فَصَلُّوا قُعُودًا  

nasai-kubra:7473Abū al-Ashʿath > Muḥammad b. ʿAbd al-Raḥman al-Ṭufāwī > Ayyūb > al-Zuhrī > Anas b. Mālik

[Machine] That the Prophet ﷺ was thrown from his horse and injured his side, so they went in to check on him. He prayed with them while seated, and they stood up. He gestured to them to sit down. When he completed his prayer, he said, "Verily, the imam is to be followed. When he says 'Allahu Akbar' then say 'Allahu Akbar,' and when he bows, then bow, and when he prostrates, then prostrate, and when he prays while standing, then pray standing, and when he prays while seated, then pray seated, all together."  

الكبرى للنسائي:٧٤٧٣أَخْبَرَنَا أَبُو الْأَشْعَثِ قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الرَّحْمَنِ الطُّفَاوِيُّ قَالَ حَدَّثَنَا أَيُّوبُ عَنِ الزُّهْرِيِّ عَنْ أَنَسِ بْنِ مَالِكٍ

أَنَّ النَّبِيَّ ﷺ صُرِعَ عَنْ فَرَسِهِ فَجُحِشَ جَنْبُهُ فَدَخَلُوا عَلَيْهِ يَعُودُونَهُ فَصَلَّى بِهِمْ قَاعِدًا وَقَامُوا فَأَوْمَأَ إِلَيْهِمْ أَنِ اقْعُدُوا فَلَمَّا قَضَى صَلَاتَهُ قَالَ «إِنَّمَا الْإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا سَجَدَ فَاسْجُدُوا وَإِذَا صَلَّى قَائِمًا فَصَلَّوْا قِيَامًا وَإِذَا صَلَّى قَاعِدًا فَصَلَّوْا قُعُودًا أَجْمَعُونَ»
