أَخْبَرَنَا أَبُو النُّعْمَانِ ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ ، حَدَّثَنَا خَالِدٌ ، عَنْ أَنَسِ بْنِ سِيرِينَ ، قَالَ : كَانَتْ أُمُّ وَلَدٍ لِأَنَسِ بْنِ مَالِكٍ اسْتُحِيضَتْ، فَأَمَرُونِي أَنْ أَسْتَفْتِيَ ابْنَ عَبَّاسٍ رَضِيَ اللهُ عَنْهُمَا فَسَأَلْتُهُ، فَقَالَ :" إِذَا رَأَتْ الدَّمَ الْبَحْرَانِيَّ، فَلَا تُصَلِّي، فَإِذَا رَأَتْ الطُّهْرَ، فَلْتَغْتَسِلْ وَلْتُصَلِّ "

Abu Al-Numan told us, Yazid bin Zurayi told us, Khaled told us, on the authority of Anas bin Sirin, he said: She was the mother of a son of Anas bin Malik. She had her menstrual period, so they ordered me to consult Ibn Abbas, may God be pleased with them both, and I asked him, and he said: “If she sees blood in the blood, then she should not pray. If she feels pure, let her wash and pray.”
