حَدَّثَنِي إِسْحَاقُ، حَدَّثَنَا ابْنُ نُمَيْرٍ، أَخْبَرَنَا هِشَامٌ، وَحَدَّثَنِي مُحَمَّدٌ، قَالَ سَمِعْتُ عُثْمَانَ بْنَ فَرْقَدٍ، قَالَ سَمِعْتُ هِشَامَ بْنَ عُرْوَةَ، يُحَدِّثُ عَنْ أَبِيهِ، أَنَّهُ سَمِعَ عَائِشَةَ ـ رضى الله عنها ـ تَقُولُ ‏{‏وَمَنْ كَانَ غَنِيًّا فَلْيَسْتَعْفِفْ وَمَنْ كَانَ فَقِيرًا فَلْيَأْكُلْ بِالْمَعْرُوفِ‏}‏ أُنْزِلَتْ فِي وَالِي الْيَتِيمِ الَّذِي يُقِيمُ عَلَيْهِ، وَيُصْلِحُ فِي مَالِهِ، إِنْ كَانَ فَقِيرًا أَكَلَ مِنْهُ بِالْمَعْرُوفِ‏.‏
