Arabic (Original)
حَدَّثَنَا حَسَنٌ حَدَّثَنَا ابْنُ لَهِيعَةَ عَنْ زَبَّانَ عَنْ سَهْلِ بْنِ مُعَاذٍ عَنْ أَبِيهِ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ كَانَ يَقُولُ الضَّاحِكُ فِي الصَّلَاةِ وَالْمُلْتَفِتُ وَالْمُفَقِّعُ أَصَابِعَهُ بِمَنْزِلَةٍ وَاحِدَةٍ.
English Translation
