باب مَنْ وَقَعَ عَلَى امْرَأَتِهِ وَهِيَ حَائِضٌ
Sunan Ibn Majah 650
It was narrated that Ibn 'Abbas said:
"If a man had intercourse with his wife while she was menstruating, the Prophet commanded him to give half a Dinar in charity."
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ الْجَرَّاحِ، حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ عَبْدِ الْكَرِيمِ، عَنْ مِقْسَمٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ كَانَ الرَّجُلُ إِذَا وَقَعَ عَلَى امْرَأَتِهِ وَهِيَ حَائِضٌ أَمَرَهُ النَّبِيُّ ـ صلى الله عليه وسلم ـ أَنْ يَتَصَدَّقَ بِنِصْفِ دِينَارٍ ‏.‏
