Five are the beasts for killing which there is no sin for the Muhrim: crows, kites, scorpions, rats and wild dogs. (Using translation from Muslim 1199b)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ «خَمْسٌ لَيْسَ عَلَى الْمُحْرِمِ فِي قَتْلِهِنَّ جُنَاحٌ الْغُرَابُ وَالْحِدَأَةُ وَالْعَقْرَبُ وَالْفَأْرَةُ وَالْكَلْبُ الْعَقُورُ»
