Sa’ad from Ahmad from Musa ibn al-Qasim and Abu Qatadah from Ali ibn Ja’far from his brother عليه السلام, peace be upon him, who said: I asked Imam al-Kadhim عليه السلام about a woman who leads other women in prayer, what is the limit of how loud her voice should be in recitation and takbir? Imam عليه السلام said: “As much as she can hear herself.”
