وَ رَوَى إِبْرَاهِيمُ بْنُ مَيْمُونٍ عَنِ اَلصَّادِقِ عَلَيْهِ اَلسَّلاَمُ: فِي اَلرَّجُلِ يَؤُمُّ اَلنِّسَاءَ لَيْسَ مَعَهُنَّ رَجُلٌ فِي اَلْفَرِيضَةِ قَالَ «نَعَمْ وَ إِنْ كَانَ مَعَهُ صَبِيٌّ فَلْيَقُمْ إِلَى جَانِبِهِ.
Ibrahim ibn Maymun narrated from Imam Jafar ibn Muhammad Al-Sadiq عليه السلام regarding a man leading women in the obligatory prayer, with no other man present. Imam عليه السلام said: "Yes, he may lead them, and if there is a boy present, he should stand beside him."
