Abdur Rahman bin 'Abdullah bin 'Utba عبد الرحمن بن عبد الله بن عتبة المسعودي · The Book on Salat (Prayer)

"Al-Mughirah bin Shu'bah les us in Salat. When he prayed two Rak'ah he stood without sitting. Those who were behind him said 'Subhan Allah' and he indicated to them that they should stand. He said the Taslim when he had finished his Salat and he performed two prostrations of As-Sahw, and said the Taslim. He said that Allah's Messenger did this."
