ابن ماجة:٣١٢حَدَّثَنَا يَعْقُوبُ بْنُ حُمَيْدِ بْنِ كَاسِبٍ حَدَّثَنَا الْمُغِيرَةُ بْنُ عَبْدِ الرَّحْمَنِ وَعَبْدُ اللَّهِ بْنُ رَجَاءٍ الْمَكِّيُّ عَنْ مُحَمَّدِ بْنِ عَجْلاَنَ عَنِ الْقَعْقَاعِ بْنِ حَكِيمٍ عَنْ أَبِي صَالِحٍ عَنْ أَبِي هُرَيْرَةَ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا اسْتَطَابَ أَحَدُكُمْ فَلاَ يَسْتَطِبْ بِيَمِينِهِ لِيَسْتَنْجِ بِشِمَالِهِ
