Muhammad ibn Ali ibn Mahbub from Ya'qub ibn Yazid from Muhammad ibn Sinan from Abdillah ibn Muskan who said: I sent to Imam عليه السلام a question from the questions of Ibrahim, which he was to deliver to Ibn Sadeer. So he asked Imam عليه السلام about it while Ibrahim ibn Maymun was sitting regarding a man leading women in prayer. Imam عليه السلام said: “Yes.” I said: “Ask Imam عليه السلام about them when there are young boys with them, who have not yet reached puberty. Do they stand with them in the same row, or do they stand in front of them?” Imam عليه السلام said: “No, rather they stand in front of them, even if they are slaves.”
