"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."
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ عَبْدِ الرَّحْمَنِ، أَخْبَرَنَا يَزِيدُ بْنُ هَارُونَ، عَنِ الْمَسْعُودِيِّ، عَنْ زِيَادِ بْنِ عِلاَقَةَ، قَالَ صَلَّى بِنَا الْمُغِيرَةُ بْنُ شُعْبَةَ فَلَمَّا صَلَّى رَكْعَتَيْنِ قَامَ وَلَمْ يَجْلِسْ فَسَبَّحَ بِهِ مَنْ خَلْفَهُ فَأَشَارَ إِلَيْهِمْ أَنْ قُومُوا فَلَمَّا فَرَغَ مِنْ صَلاَتِهِ سَلَّمَ وَسَجَدَ سَجْدَتَىِ السَّهْوِ وَسَلَّمَ وَقَالَ هَكَذَا صَنَعَ رَسُولُ اللَّهِ صلى الله عليه وسلم . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ . وَقَدْ رُوِيَ هَذَا الْحَدِيثُ مِنْ غَيْرِ وَجْهٍ عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ عَنِ النَّبِيِّ صلى الله عليه وسلم .
