أَخْبَرَنَا مُحَمَّدُ بْنُ عِيسَى، حَدَّثَنَا مُعْتَمِرٌ، عَنْ أَبِيهِ، قَالَ: قُلْتُ لِقَتَادَةَ: "امْرَأَةٌ كَانَ حَيْضُهَا مَعْلُومًا، فَزَادَتْ عَلَيْهِ خَمْسَةَ أَيَّامٍ، أَوْ أَرْبَعَةَ أَيَّامٍ، أَوْ ثَلَاثَةَ أَيَّامٍ ؟، قَالَ: تُصَلِّي، قُلْتُ: يَوْمَيْنِ ؟، قَالَ: ذَاكَ مِنْ حَيْضِهَا"، وَسَأَلْتُ ابْنَ سِيرِينَ، قَالَ: "النِّسَاءُ أَعْلَمُ بِذَلِكَ".
It is narrated from Mu'tamir (bin Sulaiman) that his father asked Qatadah: A woman who knows the days of her menstruation, and if blood continues to flow for five, four, or three more days, what should she do? He replied: She should perform prayers. Sulaiman said: If the blood continues for two days? He replied: This is still menstrual blood. He said: And I asked Imam Ibn Sirin, may Allah have mercy on him, and he said: Women know this matter better.
