"A man said: "O Messenger of Allah, what animals may we kill when we are in Ihram?' He said: "there are five for which there is no sin in killing them: Kites, crows, mice, scorpions and vicious dogs.'" (Using translation from Nasāʾī 2833)
رَجُلٌ يَا رَسُولَ اللهِ مَا نَقْتُلُ مِنَ الدَّوَابِّ إِذَا أَحْرَمْنَا؟ فَقَالَ خَمْسٌ لَا جُنَاحَ عَلَى مَنْ قَتَلَهُنَّ فِي قَتْلِهِنَّ الْحِدَأَةُ وَالْفَأْرَةُ وَالْغُرَابُ وَالْعَقْرَبُ وَالْكَلْبُ الْعَقُورُ
