Hadith 9

Bulugh al-Maram

Book 7: Business Transactions
وَعَنْ أَبِي هُرَيْرَةَ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ إِذَا وَقَعَتْ اَلْفَأْرَةُ فِي اَلسَّمْنِ, فَإِنْ كَانَ جَامِداً فَأَلْقُوهَا وَمَا حَوْلَهَا, وَإِنْ كَانَ مَايِعًا فَلَا تَقْرَبُوهُ } رَوَاهُ أَحْمَدُ, وَأَبُو دَاوُدَ, وَقَدْ حَكَمَ عَلَيْهِ اَلْبُخَارِيُّ وَأَبُو حَاتِمٍ بِالْوَهْمِ 1‏ .‏
Abu Hurairah (RA):

Allah's Messenger (ﷺ) said: "If a mouse falls into ghee which is solid, throw the mouse and what is surrounding it away; but if it is in a liquid state do not go near it." [Ahmad and Abu Dawud reported it; al-Bukhari and Abu Hatim ruled it to be Wahm (an error) (in reporting it from Abu Hurairah)].
