bayhaqi:13922Mālik > Yaḥyá b. Saʿīd > Abū Nahshal al-Aswad

البيهقي:١٣٩٢٢وَبِإِسْنَادِهِ قَالَ ثنا مَالِكٌ عَنْ يَحْيَى بْنِ سَعِيدٍ أَنَّ أَبَا نَهْشَلٍ الْأَسْوَدَ قَالَ لِلْقَاسِمِ بْنِ مُحَمَّدٍ إِنِّي رَأَيْتُ جَارِيَةً لِي مُنْكَشِفًا عَنْهَا وَهِيَ فِي الْقَمَرِ فَجَلَسْتُ مِنْهَا مَجْلِسَ الرَّجُلِ مِنِ امْرَأَتِهِ فَقَالَتْ

إِنِّي حَائِضٌ فَلَمْ أَمَسَّهَا فَأَهَبُهَا لِابْنِي يَطَؤُهَا؟ فَنَهَاهُ الْقَاسِمُ عَنْ ذَلِكَ
