أَخْبَرَنَا نُعَيْمُ بْنُ حَمَّادٍ ، حَدَّثَنَا عَبْدُ الْعَزِيزِ هُوَ ابْنُ مُحَمَّدٍ ، عَنْ سُهَيْلٍ ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي سَعِيدٍ ، عَنْ أَبِيهِ ، عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ :" إِذَا تَثَاءَبَ أَحَدُكُمْ، فَلْيَشُدَّ يَدَهُ، فَإِنَّ الشَّيْطَانَ يَدْخُلُ ".
قَالَ أَبُو مُحَمَّد : يَعْنِي عَلَى فِيهِ
