أَخْبَرَنَا عَمْرُو بْنُ عَوْنٍ، عَنْ خَالِدِ بْنِ عَبْدِ اللَّهِ، عَنِ ابْنِ أَبِي لَيْلَى، عَنْ عَطَاءٍ، عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا، قَالَ: «إِذَا وَقَعَ عَلَى امْرَأَتِهِ وَهِيَ حَائِضٌ، فَعَلَيْهِ أَنْ يَتَصَدَّقَ بِدِينَارٍ»
Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: When a man has intercourse with his wife while she is menstruating, he must give one dinar in charity. Imam Ibrahim (may Allah have mercy on him) said: And he must also seek forgiveness.
