The Messenger of Allah ﷺ fell ill, so we prayed behind him while he was seated, and Abu Bakr was calling out the takbir to make the people hear it. The Prophet ﷺ turned toward us and saw us standing, so he gestured to us, and we sat down and prayed seated, following his prayer.When he had finished with the salam, he said, "You were about to do as the Persians and Romans do, standing over their kings while they remain seated. Do not do that. Follow your imams. If he prays standing, then pray standing, and if he prays seated, then pray seated."
حدثنا محمد بن رمح المصري أنبأنا الليث بن سعد عن أبي الزبير
اشتكى رسول الله ﷺ فصلينا وراءه وهو قاعد وأبو بكر يكبر يسمع الناس تكبيره فالتفت إلينا فرآنا قياما فأشار إلينا فقعدنا فصلينا بصلاته قعودا فلما سلم قال إن كدتم أن تفعلوا فعل فارس والروم يقومون على ملوكهم وهم قعود فلا تفعلوا ائتموا بأئمتكم إن صلى قائما فصلوا قياما وإن صلى قاعدا فصلوا قعودا
