Ziyad bin Haqah narrated: "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".
The hadith also teaches us about humility and patience during prayer, as well as respect for those who are leading prayers or reciting Quranic verses aloud. When those behind him said 'Subhan Allah', he indicated to them that they should stand instead of interrupting his prayer with their words. This teaches us that we should be respectful during prayers, even if we feel moved by something being said or done during a prayer session.
