حَدَّثَنَا عِيسَى بْنُ حَمَّادٍ الْمِصْرِيُّ، أَنْبَأَنَا اللَّيْثُ بْنُ سَعْدٍ، عَنْ جَعْفَرِ بْنِ رَبِيعَةَ، عَنْ عَبْدِ الرَّحْمَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏"‏ إِذَا أَحَدُكُمْ قَرَّبَ إِلَيْهِ مَمْلُوكُهُ طَعَامًا قَدْ كَفَاهُ عَنَاءَهُ وَحَرَّهُ فَلْيَدْعُهُ فَلْيَأْكُلْ مَعَهُ فَإِنْ لَمْ يَفْعَلْ فَلْيَأْخُذْ لُقْمَةً فَلْيَجْعَلْهَا فِي يَدِهِ ‏"‏ ‏.‏
