Sahih Muslim Book - 15, Hadith - 2872

وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ - رضى الله عنهما - أَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- قَالَ « خَمْسٌ مِنَ الدَّوَابِّ لَيْسَ عَلَى الْمُحْرِمِ فِى قَتْلِهِنَّ جُنَاحٌ الْغُرَابُ وَالْحِدَأَةُ وَالْعَقْرَبُ وَالْفَارَةُ وَالْكَلْبُ الْعَقُورُ ».

It was narrated form Ibn Umar [may Allah be pleased with them] that the Messenger of Allah (SAW) said: “There are five creatures for which there is no sin on the one who kills them: Mice, scorpions, crows, kites and vicious dogs.”
