AHMAD 19595:
from Abū Mūsá al-Ashʿarī —
[Machine] The Messenger of Allah ﷺ taught us our prayers and Sunnahs, and he said, "Indeed, the imam is to be followed. So when he says 'Allahu Akbar,' say 'Allahu Akbar,' and when he says, 'not of those who have evoked [Your] anger or of those who are astray' [Al-Fatiha 7], say 'Ameen,' as Allah, the Most High, will answer your supplication. And when he bows, bow, and when he raises his head, raise yours, and when he says, 'Allah hears whoever praises Him,' say, 'Our Lord, to You is all praise,' as Allah hears you. And when he prostrates, prostrate, and when he raises his head, raise yours. Indeed, the imam prostrates before you and raises before you." The Messenger of Allah ﷺ said, "So do, as such is done."

عن ابو موسى الاشعري —
عَلَّمَنَا رَسُولُ اللهِ ﷺ صَلَاتَنَا وَسُنَّتَنَا فَقَالَ إِنَّمَا الْإِمَامُ لِيُؤْتَمَّ بِهِ فَإِذَا كَبَّرَ فَكَبِّرُوا وَإِذَا قَالَ {غَيْرِ الْمَغْضُوبِ عَلَيْهِمْ وَلَا الضَّالِّينَ} [الفاتحة 7] فَقُولُوا آمِينَ يُجِبْكُمُ اللهُ تَعَالَى وَإِذَا رَكَعَ فَارْكَعُوا وَإِذَا رَفَعَ فَارْفَعُوا وَإِذَا قَالَ سَمِعَ اللهُ لِمَنْ حَمِدَهُ فَقُولُوا رَبَّنَا لَكَ الْحَمْدُ يَسْمَعِ اللهُ لَكُمْ وَإِذَا سَجَدَ فَاسْجُدُوا وَإِذَا رَفَعَ فَارْفَعُوا؛ فَإِنَّ الْإِمَامَيَسْجُدُ قَبْلَكُمْ وَيَرْفَعُ قَبْلَكُمْ قَالَ رَسُولُ اللهِ ﷺ فَتِلْكَ بِتِلْكَ
