Sunan Ibn Majah, Hadith 3089 ⓘ
It was narrated from Abu Sa’eed that the Prophet said: ‘The one in Ihram may kill the snake, the scorpion, the aggressive predator, the vicious dog and the harmful mouse.” It was said to him: “Why is it said that they are harmful?” He said:* “Because the Messenger of Allah woke up because of one, and it had taken the wick (of the lamp) to burn down the house.”
حَدَّثَنَا أَبُو كُرَيْبٍ، حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ، عَنْ يَزِيدَ بْنِ أَبِي زِيَادٍ، عَنِ ابْنِ أَبِي نُعْمٍ، عَنْ أَبِي سَعِيدٍ، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ أَنَّهُ قَالَ " يَقْتُلُ الْمُحْرِمُ الْحَيَّةَ وَالْعَقْرَبَ وَالسَّبُعَ الْعَادِيَ وَالْكَلْبَ الْعَقُورَ وَالْفَأْرَةَ الْفُوَيْسِقَةَ " . فَقِيلَ لَهُ لِمَ قِيلَ لَهَا الْفُوَيْسِقَةُ قَالَ لأَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ اسْتَيْقَظَ لَهَا وَقَدْ أَخَذَتِ الْفَتِيلَةَ لِتُحْرِقَ بِهَا الْبَيْتَ .
