البيهقي:٢٨٠٢ – وَحَدَّثَنَا أَبُو الْحَسَنِ مُحَمَّدُ بْنُ الْحُسَيْنِ الْعَلَوِيُّ ثنا أَبُو مُحَمَّدٍ الْحَسَنُ بْنُ الْحُسَيْنِ بْنِ مَنْصُورٍ السِّمْسَارُ ثنا حَامِدُ بْنُ أَبِي حَامِدٍ الْمُقْرِئُ ثنا إِسْحَاقُ بْنُ سُلَيْمَانَ الرَّازِيُّ ثنا سُفْيَانُ بْنُ سَعِيدٍ عَنْ يَحْيَى بْنِ سَعِيدٍ عَنِ الْأَعْرَجِ عَنْ عَبْدِ اللهِ ابْنِ بُحَيْنَةَ

أَنَّ رَسُولَ اللهِ ﷺ قَامَ فِي الرَّكْعَتَيْنِ فَلَمْ يَجْلِسْ ثُمَّ سَجَدَ سَجْدَتَيِ السَّهْوِ أَخْرَجَاهُ مِنْ حَدِيثِ يَحْيَى بْنِ سَعِيدٍ الْأَنْصَارِيِّ
