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."
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 ‏.‏
