From Maimunah that a mouse fell in some cooking fat and died. So the Prophet ﷺ was asked about that and he said: "Remove it (the mouse) and what was around it and then eat it (the fat)." He said: There are something on this topic from Abu Hurairah.
أَنَّ فَأْرَةً وَقَعَتْ فِي سَمْنٍ فَمَاتَتْ فَسُئِلَ عَنْهَا النَّبِيُّ ﷺ فَقَالَ أَلْقُوهَا وَمَا حَوْلَهَا وَكُلُوهُ قَالَ وَفِي الْبَابِ عَنْ أَبِي هُرَيْرَةَ
