عَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا وَقَعَتِ الْفَأْرَةُ فِي السَّمْنِ فَإِنْ كَانَ جَامِدًا فَأَلْقُوهَا وَمَا حَوْلَهَا وَإِنْ كَانَ مَائِعًا فَلَا تَقْرَبُوهُ» . رَوَاهُ أَحْمد وَأَبُو دَاوُد وَرَوَاهُ الدَّارمِيّ عَن ابْن عَبَّاس

Abu Huraira reported God’s messenger as saying, "When a mouse falls into clarified butter which, is solid throw the mouse and what is around it away; but if it is in a liquid state do not go near it." Ahmad and Abu Dawud transmitted it, and Darimi transmitted it on the authority of Ibn ‘Abbas.
