أَبُو سَلَمَةَ ، عَنْ
أَبِي هُرَيْرَة ، عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّم قَالَ :
" إِذَا كَبَّرَ الْإِمَامُ فَكَبِّرُوا ، وَإِذَا رَكَعَ فَارْكَعُوا ، وَإِذَا سَجَدَ فَاسْجُدُوا ، وَإِنْ صَلَّى جَالِسًا فَصَلُّوا جُلُوسًا " .
It is narrated with the previous chain that the Prophet Muhammad (peace be upon him) said: When the imam says the takbeer, you should also say the takbeer; when he bows (in ruku‘), you should also bow; when he prostrates, you should also prostrate; and when he prays sitting, then all of you should also pray sitting.
