Volume 1, Book 11, Number 689:
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 hamida"; and if he pros –
trates, 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).
