" خَمْسٌ لاَ جُنَاحَ عَلَى مَنْ قَتَلَهُنَّ الْحِدَأَةُ وَالْغُرَابُ وَالْفَأْرَةُ وَالْعَقْرَبُ وَالْكَلْبُ الْعَقُورُ "
It was narrated that Ibn Umar said: "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.'"
