Arabic (Original)
قَالَ قَرَأْتُ عَلَى عَبْدِ الرَّحْمَنِ : مَالِكٌ عَنْ هِشَامِ بْنِ عُرْوَةَ عَنْ أَبِيهِ عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهَا قَالَتْ صَلَّى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي بَيْتِهِ وَهُوَ شَاكٍ فَصَلَّى جَالِسًا وَصَلَّى وَرَاءَهُ قَوْمٌ قِيَامًا فَأَشَارَ إِلَيْهِمْ أَنْ اجْلِسُوا فَلَمَّا انْصَرَفَ قَالَ إِنَّمَا جُعِلَ الْإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا رَفَعَ فَارْفَعُوا وَإِذَا صَلَّى جَالِسًا فَصَلُّوا جُلُوسًا.
English Translation
It is related, through Malik, from Hisham ibn Urwah, from his father, from Aisha, wife of the Prophet (peace and blessings be upon him), that she said: The Messenger of Allah (peace and blessings be upon him) prayed in his house while he was unwell, praying seated, while some people prayed behind him standing. He gestured to them to sit down. When he had finished, he said, "The imam is appointed only to be followed: when he bows, then bow; when he rises, then rise; and when he prays seated, then pray seated."
