البيهقي:٤٨٠٩ – وَأَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ ثنا مُحَمَّدُ بْنُ صَالِحِ بْنِ هَانِئٍ ثنا الْحُسَيْنُ بْنُ الْفَضْلِ الْبَجَلِيُّ ثنا مُسْلِمُ بْنُ إِبْرَاهِيمَ وَسُلَيْمَانُ بْنُ حَرْبٍ قَالَا ثنا جَرِيرُ بْنُ حَازِمٍ عَنْ قَيْسِ بْنِ سَعْدٍ عَنْ عَطَاءٍ

أَنَّهُ كَانَ يُوتِرُ بِثَلَاثٍ لَا يَجْلِسُ فِيهِنَّ وَلَا يَتَشَهَّدُ إِلَّا فِي آخِرِهِنَّ
