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. (Using translation from Abū Dāʾūd 1846)
سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ يُقْتَلُ مِنَ الدَّوَابِّ خَمْسٌ لَا جُنَاحَ عَلَى مَنْ قَتَلَهُنَّ فِي قَتْلِهِنَّ الْغُرَابُ وَالْحِدَأَةُ وَالْعَقْرَبُ وَالْكَلْبُ الْعَقُورٌ وَالْفَأْرَةُ
