One who has intercourse with his wife when she is menstruating

Sunan Ibn Majah · Book 1 · Hadith 650

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 ‏.‏

It was narrated that Ibn 'Abbas said: "If a man had intercourse with his wife while she was menstruating, the Prophet (ﷺ) commanded him to give half a Dinar in charity."
