“The Messenger of Allah ﷺ fell ill, and we prayed behind him while he was sitting down, and Abu Bakr was saying the Takbir so that the people could hear them. He turned to us and saw us standing, so he gestured to us to sit down. When he had said the Salam, he said: ‘You were about to do the action of the Persians and Romans, who remain standing while their kings are seated. Do not do that. Follow the lead of your Imam; if he prays standing, then pray standing, and if he prays sitting down, then pray sitting down.’” (Using translation from Ibn Mājah 1240)   

أَنَّهُ قَالَ اشْتَكَى رَسُولُ اللهِ ﷺ فَصَلَّيْنَا وَرَاءَهُ وَهُوَ قَاعِدٌ وَأَبُو بَكْرٍ يُكَبِّرُ لِيُسْمِعَ النَّاسَ تَكْبِيرَهُ فَالْتَفَتَ إِلَيْنَا فَرَآنَا قِيَامًا فَأَشَارَ إِلَيْنَا فَقَعَدْنَا فَصَلَّيْنَا بِصَلَاتِهِ قُعُودًا فَلَمَّا سَلَّمَ قَالَ إِنْ كِدْتُمْ آنِفًا تَفْعَلُونَ فِعْلَ فَارِسَ وَالرُّومِ؛ يَقُومُونَ عَلَى مُلُوكِهِمْ وَهُمْ قُعُودٌ فَلَا تَفْعَلُوا ائْتَمُّوا بِأَئِمَّتِكُمْ إِنْ صَلَّى قَائِمًا فَصَلُّوا قِيَامًا وَإِنْ صَلَّى قَاعِدًا فَصَلُّوا قُعُودًا  

[Machine] When the Prophet ﷺ fell ill with the illness that he passed away from, he mentioned in regards to his matter that Abu Bakr should lead the prayer. Abu Bakr started leading the prayer and the Prophet ﷺ sat on his side and prayed, while Abu Bakr informed the people.  

لَمَّا مَرِضَ النَّبِيُّ ﷺ مَرَضَهُ الَّذِي مَاتَ فِيهِ فَذَكَرَ الْحَدِيثَ فِي أَمْرِهِ أَنْ يُصَلِّي أَبُو بَكْرٍ وَصَلَاةُ أَبِي بَكْرٍ وَخُرُوجُهُ قَالَتْ فَلَمَّا رَآهُ أَبُو بَكْرٍ ذَهَبَ يَتَآخَرُ فَأَشَارَ إِلَيْهِ أَنْ صَلِّ فَقَامَ أَبُو بَكْرٍ وَقَعَدَ رَسُولُ اللهِ ﷺ إِلَى جَنْبِهِ يُصَلِّي وَأَبُو بَكْرٍ يُسْمِعُ النَّاسَ
