حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ قَالَ حَدَّثَنَا عَبْدُ الرَّزَّاقِ قَالَ أَخْبَرَنَا مَعْمَرٌ عَنْ هَمَّامِ بْنِ مُنَبِّهٍ عَنْ أَبِي هُرَيْرَةَ عَنْ النَّبِيِّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ إِنَّمَا جُعِلَ الْإِمَامُ لِيُؤْتَمَّ بِهِ فَلَا تَخْتَلِفُوا عَلَيْهِ فَإِذَا رَکَعَ فَارْکَعُوا وَإِذَا قَالَ سَمِعَ اللَّهُ لِمَنْ حَمِدَهُ فَقُولُوا رَبَّنَا لَکَ الْحَمْدُ وَإِذَا سَجَدَ فَاسْجُدُوا وَإِذَا صَلَّی جَالِسًا فَصَلُّوا جُلُوسًا أَجْمَعُونَ وَأَقِيمُوا الصَّفَّ فِي الصَّلَاةِ فَإِنَّ إِقَامَةَ الصَّفِّ مِنْ حُسْنِ الصَّلَاةِ
صحیح بخاری · Hadith 722
Narrated Abu Huraira: The Prophet said, "The Imam is (appointed) to be followed. So do not differ from him, bow when he bows, and say, "Rabbana-lakal hamd" if he says "Sami`a l-lahu liman hamidah"; and if he prostrates, prostrate (after him), and if he prays sitting, pray sitting all together, and straighten the rows for the prayer, as the straightening of the rows is amongst those things which make your prayer a correct and perfect one. (See Hadith No. 657).
