Women reciting aloud in the Jahriyyah (Audible) Prayers
In the congregational prayer the Imam recites loudly in Fajr, Maghrib and Ishaa. Many women think that if she is praying alone at home she can’t pray loudly.
Ibn Baz was asked about the ruling of a woman praying or reciting the Qur’ân aloud in the Jahriyyah prayers. He answered: Allâh prescribed for his servants to recite aloud in the Fajr prayer, the first and second Rak’ah of Maghrib and Ishaa prayers. This ruling is general for men and women. This is because the legal rules are general, except for what has been specified by proof to be for men apart from the women.
This is a Sunnah. It is not obligatory. If you leave it it’s fine, but you are neglecting a Sunnah act. Whoever acts upon the Sunnah of the Prophet will be rewarded.
Shaykh bin ‘Uthaymeen was asked the same question to which he answered, “One should consider the following: Whichever case makes her more energetic and more submissive then let her do that. If it is better for her Khushu’ (submissiveness and humbleness) in the Salât to recite quietly, then she will recite quietly and if it is better for her Khushu’ to offer aloud then she recites aloud.
This is the case if there was no one around her who can hear her of other than her mahram, otherwise she should recite silently, because it is not permissible for the woman to raise her voice in the presence of men. His evidence is the following hadith: The Prophet said, “The Tasbeeh (saying سبحان الله) is for men, and clapping is for women” in another narration, “during Salaat” (Al Bukhaari and Muslim)
This is also the answer to those who question why ladies can’t give lectures to men. It causes fitnah for the men. He is following the opinion of the Hanbali’s. How much should she raise her voice? The limit is in the middle, not very high and not very low. The minimum is hearing herself and the maximum is the people in the same room can hear her.
