ابن ماجة:٣١٠ – حَدَّثَنَا هِشَامُ بْنُ عَمَّارٍ حَدَّثَنَا عَبْدُ الْحَمِيدِ بْنُ حَبِيبِ بْنِ أَبِي الْعِشْرِينَ حَدَّثَنَا الأَوْزَاعِيُّ عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ أَبِي قَتَادَةَ أَخْبَرَنِي أَبِي

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ إِذَا بَالَ أَحَدُكُمْ فَلاَ يَمَسَّ ذَكَرَهُ بِيَمِينِهِ وَلاَ يَسْتَنْجِ بِيَمِينِهِ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ إِبْرَاهِيمَ حَدَّثَنَا الْوَلِيدُ بْنُ مُسْلِمٍ حَدَّثَنَا الأَوْزَاعِيُّ بِإِسْنَادِهِ نَحْوَهُ
