What is the ruling regarding women dancing only in front of other women?

Praise be to Allah, the Lord of the World; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

Women's dancing only among women is permissible as long as it does not tempt other women and free from Haram matters such as music or raising their voices during the dance and singing so loud that alien men can hear them, etc. In addition, they should cover themselves properly so that no part of their Awrah (those body parts which must be covered) comes into view during the dance.
Allah knows best.
