It is narrated from Hazrat Abu Saeed (may Allah be pleased with him) that once some women said to the Prophet (peace and blessings be upon him): "O Messenger of Allah (peace and blessings be upon him)! The men dominate your gatherings, so please appoint a day for us as well, so that we may come to you?" The Prophet (peace and blessings be upon him) promised them a specific time, and there he preached and advised them, and said: "If any woman among you has three children who die, they will become a barrier for her from Hell." A woman asked: "What if there are two? For I have lost two children." The Prophet (peace and blessings be upon him) said: "Even if there are two, the same ruling applies."
