8 - حَدَّثَنا الحُسَيْنِ بْنِ أَحْمَدِ بْنِ إِدْرِيس رَضِىَ اللهُ عَنْهُ قالَ: حَدَّثَنا أَبي، عَن مُحَمَّدِ بْنِ أَحْمَدِ بْنِ يَحْيَى بْنِ عِمْران الأَشْعَرِيِّ، عَن إِبْراهيمِ بْنِ هاشِم وَغَيْرِهِ، عَن صَفْوان بْنِ يَحْيَى، عَن أَبي الحَسَن a.sُ أَنَّهُ قالَ نهى رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَآلِهِ أَن يجيب الرَّجُل أَحَداً وَهُوَعَلَى الغائط أَوْ يُكَلِّمَهُ حَتّى يَفرَغُ.
