البيهقي:٥٨٨٢ – وَأَخْبَرَنَا أَبُو الْحَسَنِ بْنُ عَبْدَانَ أنبأ أَحْمَدُ بْنُ عُبَيْدٍ الصَّفَّارُ ثنا الْحَسَنُ بْنُ سَهْلٍ الْمُجَوِّزُ ثنا عُثْمَانُ بْنُ الْهَيْثَمِ الْمُؤَذِّنُ ثنا دَاوُدُ بْنُ قَيْسٍ الْفَرَّاءُ ثنا سَعْدُ بْنُ إِسْحَاقَ عَنْ أَبِي ثُمَامَةَ الْحَنَّاطِ قَالَ لَقِيَنِي كَعْبُ بْنُ عُجْرَةَ وَأَنَا مُتَوَجِّهٌ إِلَى الْمَسْجِدِ أُشَبِّكُ بَيْنَ أَصَابِعِي فَقَالَ إِنِّي

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِذَا تَوَضَّأَ أَحَدُكُمْ ثُمَّ أَتَى الْمَسْجِدَ فَلَا يُشَبِّكْ بَيْنَ أَصَابِعِهِ فَإِنَّهُ فِي صَلَاةٍ وَكَذَلِكَ  

رَوَاهُ عَبْدُ اللهِ بْنُ وَهْبٍ وَأَبُوعَامِرٍ عَبْدُ الْمَلِكِ بْنُ عَمْرٍو عَنْ دَاوُدَ بْنِ قَيْسٍ
