Chapter on the Rules of Menstruation, Istihadah, and Nifas, and Purification From Them
وَ عَنْهُ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ مُحَمَّدِ بْنِ عَمْرِو بْنِ سَعِيدٍ عَنْ أَبِي اَلْحَسَنِ اَلرِّضَا عَلَيْهِ اَلسَّلاَمُ قَالَ: سَأَلْتُهُ عَنِ اَلطَّامِثِ كَمْ حَدُّ جُلُوسِهَا فَقَالَ« تَنْتَظِرُ عِدَّةَ مَا كَانَتْ تَحِيضُ ثُمَّ تَسْتَظْهِرُ ثَلاَثَةَ أَيَّامٍ ثُمَّ هِيَ مُسْتَحَاضَةٌ».
It is narrated from Ahmad ibn Muhammad ibn Khalid, from Muhammad ibn Amr ibn Sa’id, from Abu Al-Hasan Al-Ridha عليه السلام, who said:
I asked Imam عليه السلام about a menstruating woman, "How long should she wait?" Imam عليه السلام said: "She should wait for the duration of her usual menstruation, then add three days as a precaution. After that, she is considered to be in the state of istihadha (irregular bleeding)."
