Muwatta Imam Malik Book of General Subjects, Hadith 20

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 "

وَحَدَّثَنِي مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ بْنِ مَسْعُودٍ، عَنْ عَبْدِ اللَّهِ بْنِ عَبَّاسٍ، عَنْ مَيْمُونَةَ، زَوْجِ النَّبِيِّ ﷺ أَنَّ رَسُولَ اللَّهِ ﷺ سُئِلَ عَنِ الْفَأْرَةِ تَقَعُ فِي السَّمْنِ فَقَالَ " انْزِعُوهَا وَمَا حَوْلَهَا فَاطْرَحُوهُ " .
