البيهقي:٢١٨١٠أَخْبَرَنَا أَبُو أَحْمَدَ عَبْدُ اللهِ بْنُ مُحَمَّدِ بْنِ الْحَسَنِ الْمِهْرَجَانِيُّ أنبأ أَبُو بَكْرِ بْنُ جَعْفَرٍ الْمُزَكِّي ثنا مُحَمَّدُ بْنُ إِبْرَاهِيمَ الْبُوشَنْجِيُّ ثنا ابْنُ بُكَيْرٍ ثنا مَالِكٌ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ

أَنَّهُ قَالَ فِي أُمِّ الْوَلَدِ يُتَوَفَّى عَنْهَا سَيِّدُهَا تَعْتَدُّ بِحَيْضَةٍ وَقَدْ مَضَى فِي كِتَابِ الْعِدَّةِ مَا رُوِيَ فِيهَا مِنَ الِاخْتِلَافِ وَبِاللهِ التَّوْفِيقُ
