AHMAD 7144:
from Abū Hurayrah —
[Machine] From the Prophet ﷺ that he said: "Indeed, the Imam is meant to be followed, so when he says 'Allahu Akbar,' then all of you say 'Allahu Akbar.' And when he bows, then all of you bow. And when he says 'Sami'a Allahu liman hamidah,' then say 'Rabbana lakal hamd.' And when he prays sitting, then all of you pray sitting, all together."

عن ابو هريره —
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ إِنَّمَا الْإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا قَالَ سَمِعَ اللهُ لِمَنْ حَمِدَهُ فَقُولُوا رَبَّنَا لَكَ الْحَمْدُ فَإِذَا صَلَّى جَالِسًا فَصَلُّوا جُلُوسًا أَجْمَعِينَ
