What is the ruling on women staying in the mosque from after 'Asr prayer until 'Ishā' to read the Qur'an?

It is permissible for a woman to go out to the mosque for prayer, provided her husband gives permission, she wears modest clothing, there is no fear of temptation (fitna), and she refrains from using perfume. Similarly, it is permissible for her to remain in the mosque to study the Qur'an until the Maghrib or Isha prayer, provided she adheres to the aforementioned conditions. She will receive a great reward for doing so.
