Which is better for a woman, performing prayers in a congregation or performing prayers individually?

Answer

It is recommended for women to attend congregational prayers as evidenced by an authentic tradition from the Commander of the Faithful, Ali (AS) that women used to attend congregational prayers but they were ordered to linger their sajda (prostration) because some men were wearing tight garments but there is another authentic tradition which says that a woman's prayer at home is more virtuous than her prayer in a mosque. However, the conclusion that can be drawn from both traditions is that a woman's prayer at a place where she is not seen by non-mahram men (strangers) is more virtuous. If she can perform her prayers in a mosque without being seen by strangers, the prayer in a mosque would be more virtuous in that case.
