Malik related to me from Ibn Shihab from Ubaydullah ibn Abdullah ibn Utba ibn Masud from Abdullah ibn Abbas from Maimuna, the wife of the Prophet ﷺ that the Messenger of Allah ﷺ was asked about a mouse falling into clarified butter. He said, "Remove it and throw away what is around it "
عَنْ مَيْمُونَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّ رَسُولَ اللَّهِ ﷺ سُئِلَ عَنِ الْفَأْرَةِ تَقَعُ فِي السَّمْنِ فَقَالَ انْزِعُوهَا وَمَا حَوْلَهَا فَاطْرَحُوهُ
