In response to this question, the European Council for Fatwa and Research (ECFR) issued the following Fatwa:
The association should provide a place for women for as long as this is possible because they have the right to attend congregational prayers, Friday prayers, and Taraweeh prayers. They also have the right to participate in the mosque’s lectures. This is due to the following factors:
First: The Prophet (peace be upon him) said:
“لا تمنعوا إماء الله مساجد الله”
“Prevent not Allah’s female servants from attending the mosque” (Agreed-upon).
This hadith establishes women’s right to worship alongside men in the mosque. Furthermore, Islamic obligations originally applied to both men and women, unless one sex is exempted due to its nature.
Second, during the Prophet’s (peace be upon him) lifetime and the era of the Muslim-guided Caliphs, women used to go to mosques and perform congregational prayers, Friday prayers, and other activities.
Third, European women need spiritual and educational support, as well as a positive role in the Muslim community. This can only be accomplished in a mosque, and Ramadan is a great time to do so.
Allah Almighty knows best.
