الدارمي:٣١٠٤حَدَّثَنَا أَبُو نُعَيْمٍ حَدَّثَنَا أَبُو هَانِئٍ قَالَ سُئِلَ عَامِرٌ

عَنِ امْرَأَةٍ أَوْ رَجُلٍ تُوُفِّيَ وَتَرَكَ خَالَةً وَعَمَّةً قال لَيْسَ لَهُ وَارِثٌ وَلَا رَحِمٌ غَيْرُهُمَا فَقَالَ «كَانَ عَبْدُ اللَّهِ بْنُ مَسْعُودٍ يُنَزِّلُ الْخَالَةَ بِمَنْزِلَةِ أُمِّهِ وَيُنَزِّلُ الْعَمَّةَ بِمَنْزِلَةِ أَخِيهَا»
