The use of loudspeakers in women’s gatherings if it leads to men hearing them

Question:
May Allah reward you. The sender, Khalid Muhammad from Jizan, asks: What is the ruling on using loudspeakers in gatherings held in some schools for women? It is known that the sound can be heard from outside the school, and likewise in some wedding gatherings. What is the ruling on that? And do you have a word on this? May Allah reward you with good.

Answer:
It is not permissible to raise the voices of women in any way such that men can hear them, because of the fitnah (trial, discord or temptation) involved in that, whether that is by means of a loudspeaker or otherwise, whether it is in a school gathering or a wedding gathering. The voices of women are not to be raised such that men can hear them, especially if that is...
...singing and what is done in weddings of women singing and beating the duff (the hand drum), which is prescribed for them in that, except that it is not raised and sent out by means of a loudspeaker to the street or to the society of men, but rather that is to be within their circle and among themselves. This is what is obligatory. Yes.
