9) باب ذِكْرِ مَا يَجِبُ عَلَى مَنْ أَتَى حَلِيلَتَهُ فِي حَالِ حَيْضِهَا مَعَ عِلْمِهِ بِنَهْىِ اللَّهِ تَعَالَى
أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ شُعْبَةَ، قَالَ حَدَّثَنِي الْحَكَمُ، عَنْ عَبْدِ الْحَمِيدِ، عَنْ مِقْسَمٍ، عَنِ ابْنِ عَبَّاسٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم فِي الرَّجُلِ يَأْتِي امْرَأَتَهُ وَهِيَ حَائِضٌ يَتَصَدَّقُ بِدِينَارٍ أَوْ بِنِصْفِ دِينَارٍ .
