البيهقي:٧٦٤وَأَخْبَرَنَا أَبُو الْحَسَنِ الْمُقْرِئُ ثنا الْحَسَنُ بْنُ مُحَمَّدِ بْنِ إِسْحَاقَ نا يُوسُفُ بْنُ يَعْقُوبَ ثنا مُحَمَّدُ بْنُ أَبِي بَكْرٍ ثنا مُعَاذُ بْنُ هِشَامٍ ثنا أَبِي ثنا قَتَادَةُ وَمَطَرٌ عَنِ الْحَسَنِ عَنْ أَبِي رَافِعٍ عَنْ أَبِي هُرَيْرَةَ

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا جَلَسَ بَيْنَ شُعَبِهَا الْأَرْبَعِ ثُمَّ جَهَدَهَا فَقَدْ وَجَبَ الْغُسْلُ وَفِي حَدِيثِ مَطَرٍ وَإِنْ لَمْ يُنْزِلْ  

رَوَاهُ مُسْلِمٌ فِي الصَّحِيحِ عَنْ مُحَمَّدِ بْنِ الْمُثَنَّى وَغَيْرِهِ عَنْ مُعَاذِ بْنِ هِشَامٍ وَقَدْ ذَكَرَ أَبَانُ بْنُ يَزِيدَ وَهَمَّامُ بْنُ يَحْيَى وَابْنُ أَبِي عَرُوبَةَ عَنْ قَتَادَةَ الزِّيَادَةَ الَّتِي ذَكَرَهَا مَطَرٌ
