عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((خَمْسٌ، كُلُّهُنَّ فَاسِقَةٌ، يَقْتُلُهُنَّ الْمُحْرِمُ وَيُقْتَلْنَ فِي الْحَرَمِ: الْفَأُرَةُ، وَالْعَقْرَبُ، وَالْحَيَّةُ، وَالْكَلْبُ الْعَقُورُ، وَالْغُرَابُ))
Narrated by Sayyiduna Abdullah bin Abbas (may Allah be pleased with him): The Noble Prophet (peace and blessings be upon him) said: There are five kinds of animals that are harmful; even a person in the state of Ihram may kill them, and they may also be killed within the boundaries of the Haram: the mouse, the scorpion, the snake, the rabid dog, and the crow.
