حَدَّثَنَا عَبْدُ اللهِ بْنُ صَالِحٍ قَالَ: حَدَّثَنِي اللَّيْثُ قَالَ: حَدَّثَنِي أَبُو الزُّبَيْرِ، عَنْ جَابِرٍ قَالَ: اشْتَكَى النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، فَصَلَّيْنَا وَرَاءَهُ وَهُوَ قَاعِدٌ، وَأَبُو بَكْرٍ يُسْمِعُ النَّاسَ تَكْبِيرَهُ، فَالْتَفَتَ إِلَيْنَا فَرَآنَا قِيَامًا، فَأَشَارَ إِلَيْنَا فَقَعَدْنَا، فَصَلَّيْنَا بِصَلاَتِهِ قُعُودًا، فَلَمَّا سَلَّمَ قَالَ: ”إِنْ كِدْتُمْ لَتَفْعَلُوا فِعْلَ فَارِسَ وَالرُّومِ، يَقُومُونَ عَلَى مُلُوكِهِمْ وَهُمْ قُعُودٌ، فَلاَ تَفْعَلُوا، ائْتَمُّوا بِأَئِمَّتِكُمْ، إِنْ صَلَّى قَائِمًا فَصَلُّوا قِيَامًا، وَإِنْ صَلَّى قَاعِدًا فَصَلُّوا قُعُودًا.“
It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) became ill, so we prayed behind him while he was sitting, and Sayyiduna Abu Bakr (may Allah be pleased with him) was conveying the takbirs of the Prophet (peace and blessings of Allah be upon him) to the people. The Prophet (peace and blessings of Allah be upon him) turned and saw that we were praying standing. He (peace and blessings of Allah be upon him) gestured to us to sit, so we sat down, and then we performed the prayer sitting, following him (peace and blessings of Allah be upon him). When he (peace and blessings of Allah be upon him) finished the prayer with salam, he said: "Do not start doing as the Persians and Romans do, for they stand before their kings while their kings remain seated. Do not do so. Follow your imams. If the imam prays standing, then you should also pray standing, and if he prays sitting, then you should also pray sitting."
