أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ يَزِيدَ الْمُقْرِئُ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمٍ، عَنْ أَبِيهِ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ خَمْسٌ مِنَ الدَّوَابِّ لاَ جُنَاحَ فِي قَتْلِهِنَّ عَلَى مَنْ قَتَلَهُنَّ فِي الْحَرَمِ وَالإِحْرَامِ الْفَأْرَةُ وَالْحِدَأَةُ وَالْغُرَابُ وَالْعَقْرَبُ وَالْكَلْبُ الْعَقُورُ ‏" ‏ ‏.‏
