Ibn ‘Umar said The Prophet ﷺ was asked as to which of the creatures could be killed by a pilgrim in the sacred state. He said there are five creatures which it is not a sin for anyone to kill, outside or inside the sacred area. The Scorpion, the Crow, the Rat, the Kite and the biting Dog.
عَنْ أَبِيهِ سُئِلَ النَّبِيُّ ﷺ عَمَّا يَقْتُلُ الْمُحْرِمُ مِنَ الدَّوَابِّ فَقَالَ خَمْسٌ لاَ جُنَاحَ فِي قَتْلِهِنَّ عَلَى مَنْ قَتَلَهُنَّ فِي الْحِلِّ وَالْحَرَمِ الْعَقْرَبُ وَالْفَأْرَةُ وَالْحِدَأَةُ وَالْغُرَابُ وَالْكَلْبُ الْعَقُورُ
