وَعَن ميمونةَ أَنَّ فَأْرَةً وَقَعَتْ فِي سَمْنٍ فَمَاتَتْ فَسُئِلَ رَسُول الله صلى الله عَلَيْهِ وَسلم فَقَالَ: «ألقوها وَمَا حولهَا وكلوه» . رَوَاهُ البُخَارِيّ
Maimuna said that when a mouse fell into some clarified butter and died God's messenger was asked about it and replied, "Throw it and what is round it away and eat what is left." Bukhari transmitted it.
