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.

حَدَّثَنَا أَحْمَدُ بْنُ حَنْبَلٍ، حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، 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 " .
