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 "

Muhammad bin Issa told us, Mu`tamar told us, on the authority of his father, he said: I said to Qatada: “A woman whose menstruation was known, so she added five times more to it.” Days, four days, or three days? He said: She prays? I said: Two days? He said: That was from her menstruation. And I asked Ibn Sirin, he said: “Women are more knowledgeable about that.”
