Is it Haram for women to do Zaggareed in Islamic weddings where there are women and no music, just singing regular songs with the Duff and the Zaggareeds (which is only a loud voice from some of the women to celebrate the event with no men around?

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

There is no harm in trilling cries of joy even with high sound during feasts, occasions, etc. as long as it is done only among women, away from men and free from music.

Allah knows best.
