حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، حَدَّثَنَا سُفْيَانُ، عَنْ ابْنِ جُرَيْجٍ، عَنْ عَطَاءٍ، قَالَ: "تَسْتَغْفِرُ اللَّهَ، وَلَيْسَ عَلَيْكَ شَيْءٌ"، يَعْنِي: إِذَا وَقَعَ عَلَى امْرَأَتِهِ وَهِيَ حَائِضٌ.
It is narrated from Ata (may Allah have mercy on him): He should seek forgiveness from Allah and there is no expiation upon him. That is, when a man has intercourse with his wife during her menstrual period (there is no expiation upon him, he should just repent and seek forgiveness).
