Persian Voices: Women of Islam
There is no religious objection to such gatherings, and women of Islam have always and everywhere come together. Also, according to the Constitution, this is not objectionable.

So long as gatherings are not disruptive of religious and worldly affairs, there is no harm and no prohibition.
