Aslam

Praise be to Allah.It is permissible for

a woman to say Ameen out loud, if she is in the presence of her mahrams

and there are no “strangers” (non-mahram men) present, because a woman

is forbidden to raise her voice in the presence of non-mahram men for

fear of fitnah (temptation). But in the presence of her mahrams she

is not forbidden to do so.

Shaykh

al-Fawzaan (may Allaah preserve him) was asked about a woman speaking

aloud during prayer, and he said:

It is mustahabb for her to recite out loud in prayer,

whether it is fard (obligatory) of naafil (supererogatory) (i.e., the

prayers in which Qur’aan is to be recited out loud), so long as no non-mahram

man can hear her, lest he be tempted by her voice. But if she is in

a place where no non-mahram man can hear her, then in prayers offered

at night she should recite out loud, but if that will disturb others

then she should not recite out loud. But in the case of the prayers

that are offered during the day, she should recite silently, because

the prayers during the day are to be recited silently. So it is not

mustahabb to recite out loud in the prayers that are offered during

the day, because that goes against the Sunnah. And Allaah knows best.
