حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ ، قَالَ حَدَّثَنَا مَعْنٌ ، قَالَ حَدَّثَنَا مَالِكٌ ، عَنِ ابْنِ شِهَابٍ ، عَنْ عُبَيْدِ اللَّهِ بْنِ عَبْدِ اللَّهِ بْنِ عُتْبَةَ بْنِ مَسْعُودٍ ، عَنِ ابْنِ عَبَّاسٍ ، عَنْ مَيْمُونَةَ ، أَنَّ النَّبِيَّ صلى الله عليه وسلم سُئِلَ عَنْ فَأْرَةٍ سَقَطَتْ فِي سَمْنٍ فَقَالَ " خُذُوهَا وَمَا حَوْلَهَا فَاطْرَحُوهُ " . قَالَ مَعْنٌ حَدَّثَنَا مَالِكٌ مَا لاَ أُحْصِيهِ يَقُولُ عَنِ ابْنِ عَبَّاسٍ عَنْ مَيْمُونَةَ .
