وَ سَأَلَ عَلِيُّ بْنُ جَعْفَرٍ أَخَاهُ مُوسَى بْنَ جَعْفَرٍ عَلَيْهِمَا اَلسَّلاَمُ: عَنِ اَلْمَرْأَةِ تَؤُمُّ اَلنِّسَاءَ مَا حَدُّ رَفْعِ صَوْتِهَا بِالتَّكْبِيرِ وَ اَلْقِرَاءَةِ فَقَالَ «قَدْرُ مَا تُسْمِعُ.
Ali ibn Ja'far was asked about his brother Imam Musa ibn Jafar Al-Kadhim (a.s) about a woman leading other women in prayer: "What is the limit of raising her voice in the takbir (saying 'Allahu Akbar') and in recitation?" Imam (a.s) replied: "To the extent that they can hear her."
