Animals That May Be Killed By The Muhrim: Killing Vicious Dogs
Sunan an-Nasai
أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " خَمْسٌ لَيْسَ عَلَى الْمُحْرِمِ فِي قَتْلِهِنَّ جُنَاحٌ الْغُرَابُ وَالْحِدَأَةُ وَالْعَقْرَبُ وَالْفَأْرَةُ وَالْكَلْبُ الْعَقُورُ .
It was narrated from Ibn Umar that the Messenger of Allah said: "There are five (animals) for which there is no sin on the Muhrim if he kills them: Crows, kites, scorpions, mice and vicious dogs."
