The Messenger of Allah ﷺ rode a horse in Medina. It threw him off at the root of a date-palm. His foot was injured. We visited him to inquire about his illness. We found him praying sitting in the apartment of Aisha. We, therefore, stood, (praying) behind him. He kept silent. We again visited him to inquire about his illness. He offered the obligatory prayer sitting. We, therefore, stood (praying) behind him; he made a sign to us and we sat down. When he finished the prayer, he said: When the imam prays sitting, pray sitting; and when the imam prays standing, pray standing, and do not act as the people of Persia used to act with their chiefs (i.e. the people stood and they were sitting).  

رَكِبَ رَسُولُ اللَّهِ ﷺ فَرَسًا بِالْمَدِينَةِ فَصَرَعَهُ عَلَى جِذْمِ نَخْلَةٍ فَانْفَكَّتْ قَدَمُهُ فَأَتَيْنَاهُ نَعُودُهُ فَوَجَدْنَاهُ فِي مَشْرَبَةٍ لِعَائِشَةَ يُسَبِّحُ جَالِسًا قَالَ فَقُمْنَا خَلْفَهُ فَسَكَتَ عَنَّا ثُمَّ أَتَيْنَاهُ مَرَّةً أُخْرَى نَعُودُهُ فَصَلَّى الْمَكْتُوبَةَ جَالِسًا فَقُمْنَا خَلْفَهُ فَأَشَارَ إِلَيْنَا فَقَعَدْنَا قَالَ فَلَمَّا قَضَى الصَّلاَةَ قَالَ إِذَا صَلَّى الإِمَامُ جَالِسًا فَصَلُّوا جُلُوسًا وَإِذَا صَلَّى الإِمَامُ قَائِمًا فَصَلُّوا قِيَامًا وَلاَ تَفْعَلُوا كَمَا يَفْعَلُ أَهْلُ فَارِسَ بِعُظَمَائِهَا  

[Machine] The Prophet ﷺ was thrown off a horse onto the trunk of a palm tree and his foot was dislocated. We went to him to console him and found him praying, so we prayed with his prayer while standing. When he finished praying, he said, "Indeed, the imam is appointed to be followed, so if he prays standing, then you also pray standing. And if he prays sitting, then you also pray sitting. Do not stand while he is sitting, as the people of Persia do with their kings."  

صُرِعَ النَّبِيُّ ﷺ مِنْ فَرَسٍ عَلَى جِذْعِ نَخْلَةٍ فَانْفَكَّتْ قَدَمُهُ فَدَخَلْنَا عَلَيْهِ نَعُودُهُ فَوَجَدْنَاهُ يُصَلِّي فَصَلَّيْنَا بِصَلَاتِهِ وَنَحْنُ قِيَامٌ فَلَمَّا صَلَّى قَالَ إِنَّمَا جُعِلَ الْإِمَامُ لِيُؤْتَمَّ بِهِ فَإِنْ صَلَّى قَائِمًا فَصَلُّوا وَإِنْ صَلَّى جَالِسًا فَصَلُّوا جُلُوسًا وَلَا تَقُومُوا وَهُوَ جَالِسٌ كَمَا يَفْعَلُ أَهْلُ فَارِسٍ بِعُظَمَائِهَا
