أَنَّهُ سَأَلَ رَسُولَ اللَّهِ ﷺ مَا يَحِلُّ لِي مِنَ امْرَأَتِي وَهِيَ حَائِضٌ قَالَ لَكَ مَا فَوْقَ الإِزَارِ وَذَكَرَ مُؤَاكَلَةَ الْحَائِضِ أَيْضًا وَسَاقَ الْحَدِيثَ

أَنْهُ سَأَلَ رَسُولُ اللهِ ﷺ مَا يَحِلُّ لِي مِنِ امْرَأَتِي وَهِيَ حَائِضٌ؟ قَالَ لَكَ مَا فَوْقَ الْإِزَارِ قَالَ وَذَكَرَ مُؤَاكَلَةَ الْحَائِضِ أَيْضًا وَسَاقَ الْحَدِيثَ عَمُّهُ عَبْدُ اللهِ بْنُ سَعْدٍ الْأَنْصَارِيُّ وَقِيلَ حَرَامُ بْنُ مُعَاوِيَةَ عَنْ عَمِّهِ عَبْدِ اللهِ بْنِ سَعْدٍ الْأَنْصَارِيِّ
