3ـ أَحْمَدُ عَنِ الْحُسَيْنِ عَنْ فَضَالَةَ عَنْ حَمَّادِ بْنِ عُثْمَانَ عَنْ إِبْرَاهِيمَ بْنِ مَيْمُونٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) فِي الرَّجُلِ يَؤُمُّ النِّسَاءَ لَيْسَ مَعَهُنَّ رَجُلٌ فِي الْفَرِيضَةِ قَالَ نَعَمْ وَإِنْ كَانَ مَعَهُ صَبِيٌّ فَلْيَقُمْ إِلَى جَانِبِهِ.
3. Ahmad ibn al-Husayn has narrated from Fadalah from Hammad ibn ‘Uthaman from Ibrahim ibn Maymun who has said the following: “I once asked abu ‘Abd Allah (a.s.), about a man who leads women in obligatory Salah (prayer) where there are no other men. He (the Imam) said, ‘Yes, he can do so and if there is a child he stands up on his side.’”
