الطبراني:٩٣٦٣حَدَّثَنَا مُحَمَّدُ بْنُ النَّضْرِ الْأَزْدِيُّ ثنا مُعَاوِيَةُ بْنُ عَمْرٍو ثنا زُهَيْرٌ ثنا أَبُو إِسْحَاقَ عَنِ الْأَسْوَدِ وَعَلْقَمَةَ وَأَصْحَابِ عَبْدِ اللهِ

أَنَّ عَبْدَ اللهِ كَانَ يَقُولُ فِي السَّهْوِ يَتَحَرَّى الصَّوَابَ وَيَسْجُدُ سَجْدَتَيْنِ وَهُوَ جَالِسٌ بَعْدَ التَّسْلِيمِ
