The expiation for one who has sexual intercourse with a menstruating woman
Sunan Ibn Majah
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، وَمُحَمَّدُ بْنُ جَعْفَرٍ، وَابْنُ أَبِي عَدِيٍّ، عَنْ شُعْبَةَ، عَنِ الْحَكَمِ، عَنْ عَبْدِ الْحَمِيدِ، عَنْ مِقْسَمٍ، عَنِ ابْنِ عَبَّاسٍ، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ فِي الَّذِي يَأْتِي امْرَأَتَهُ وَهِيَ حَائِضٌ قَالَ " يَتَصَدَّقُ بِدِينَارٍ أَوْ بِنِصْفِ دِينَارٍ " .
It was narrated from Ibn 'Abbas that: The Prophet said concerning one who has intercourse with a woman when she is menstruating: "Let him give a Dinar or half a Dinar in charity."
