Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 26
وَقَالَ اَلْحَسَنُ بْنُ زِيَادٍ اَلصَّيْقَلُ: سُئِلَ أَبُو عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ كَيْفَ تُصَلِّي اَلنِّسَاءُ عَلَى اَلْجَنَائِزِ إِذَا لَمْ يَكُنْ مَعَهُنَّ رَجُلٌ فَقَالَ «يَقُمْنَ جَمِيعاً فِي صَفٍّ وَاحِدٍ وَ لاَ تَتَقَدَّمُهُنَّ اِمْرَأَةٌ» قِيلَ فَفِي صَلاَةٍ مَكْتُوبَةٍ أَ يَؤُمُّ بَعْضُهُنَّ بَعْضاً قَالَ «نَعَمْ.
Al-Hasan ibn Ziyad al-Sayqal reported that Imam Abu Abdullah عليه السلام was asked about how women should perform the funeral prayer if no men are present. Imam عليه السلام replied: "They should all stand together in a single row, and no woman should step forward as a leader." He was then asked if, during the obligatory (written) prayers, one woman may lead another. The Imam said: "Yes."
