حَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، عَنْ يُونُسَ، عَنِ الْحَسَنِ، عَنْ مَعْقِلِ بْنِ يَسَارٍ، قَالَ بَيْنَمَا هُوَ يَتَغَدَّى إِذْ سَقَطَتْ مِنْهُ لُقْمَةٌ فَتَنَاوَلَهَا فَأَمَاطَ مَا كَانَ فِيهَا مِنْ أَذًى فَأَكَلَهَا فَتَغَامَزَ بِهِ الدَّهَاقِينُ فَقِيلَ أَصْلَحَ اللَّهُ الأَمِيرَ إِنَّ هَؤُلاَءِ الدَّهَاقِينَ يَتَغَامَزُونَ مِنْ أَخْذِكَ اللُّقْمَةَ وَبَيْنَ يَدَيْكَ هَذَا الطَّعَامُ ‏.‏ قَالَ إِنِّي لَمْ أَكُنْ لأَدَعَ مَا سَمِعْتُ مِنْ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ لِهَذِهِ الأَعَاجِمِ إِنَّا كُنَّا نَأْمُرُ أَحَدَنَا إِذَا سَقَطَتْ لُقْمَتُهُ أَنْ يَأْخُذَهَا فَيُمِيطَ مَا كَانَ فِيهَا مِنْ أَذًى وَيَأْكُلَهَا وَلاَ يَدَعَهَا لِلشَّيْطَانِ ‏.‏
