Muwatta Malik, Book 20, Hadith 89 (USC-MSA)

Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, said, "There are five kinds of animal which it is not wrong for some one in ihram to kill: crows, kites, scorpions, rats and mice, and wild dogs."

حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ خَمْسٌ مِنَ الدَّوَابِّ لَيْسَ عَلَى الْمُحْرِمِ فِي قَتْلِهِنَّ جُنَاحٌ الْغُرَابُ وَالْحِدَأَةُ وَالْعَقْرَبُ وَالْفَأْرَةُ وَالْكَلْبُ الْعَقُورُ ‏" ‏ ‏.‏
