Chapter on the Rules of Menstruation, Istihadah, and Nifas, and Purification From Them
وَ بِهَذَا اَلْإِسْنَادِ عَنْ عَلِيِّ بْنِ اَلْحَسَنِ عَنِ اَلْحَسَنِ بْنِ عَلِيِّ بْنِ زِيَادٍ اَلْخَزَّازِ عَنْ أَبِي اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ قَالَ: سَأَلْتُهُ عَنِ اَلْمُسْتَحَاضَةِ كَيْفَ تَصْنَعُ إِذَا رَأَتِ اَلدَّمَ وَإِذَا رَأَتِ اَلصُّفْرَةَ وَكَمْ تَدَعُ اَلصَّلاَةَ فَقَالَ« أَقَلُّ اَلْحَيْضِ ثَلاَثَةٌ وَأَكْثَرُهُ عَشَرَةٌ وَ تَجْمَعُ بَيْنَ اَلصَّلاَتَيْنِ».
From this chain of narration from Ali ibn al-Hasan, from al-Hasan ibn Ali ibn Ziyad al-Khazzaz, from Abu al-Hasan عليه السلام, who said:
I asked Imam عليه السلام about the woman experiencing istihada (irregular bleeding), what should she do when she sees red blood, and when she sees yellowish discharge, and for how long should she refrain from prayer? Imam عليه السلام said: 'The minimum duration of menstruation is three days, and its maximum is ten days. She should combine between two prayers.'"
