حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا الأَعْمَشُ، عَنْ شَقِيقٍ، عَنْ مَسْرُوقٍ، عَنْ عَائِشَةَ ـ رضى الله عنها ـ قَالَتْ قَالَ النَّبِيُّ صلى الله عليه وسلم " إِذَا أَطْعَمَتِ الْمَرْأَةُ مِنْ بَيْتِ زَوْجِهَا غَيْرَ مُفْسِدَةٍ، لَهَا أَجْرُهَا، وَلَهُ مِثْلُهُ، وَلِلْخَازِنِ مِثْلُ ذَلِكَ، لَهُ بِمَا اكْتَسَبَ، وَلَهَا بِمَا أَنْفَقَتْ ".
