عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ يَقْتُلُ الْمُحْرِمُ الْحَيَّةَ وَالْعَقْرَبَ وَالسَّبُعَ الْعَادِيَ وَالْكَلْبَ الْعَقُورَ وَالْفَأْرَةَ الْفُوَيْسِقَةَ فَقِيلَ لَهُ لِمَ قِيلَ لَهَا الْفُوَيْسِقَةُ قَالَ لأَنَّ رَسُولَ اللَّهِ ﷺ اسْتَيْقَظَ لَهَا وَقَدْ أَخَذَتِ الْفَتِيلَةَ لِتُحْرِقَ بِهَا الْبَيْتَ
