What are the reliable Islamic websites that offer religious lessons and tests for women at home, especially if the husband prevents her from going to the mosque or religious institutes?

The questioner can enroll in the Open Islamic University, but it must be noted that indirect study does not substitute for direct study under the guidance of scholars. From them, a student of knowledge acquires manners, reverence, asceticism, and other fruits of knowledge. Reading thousands of books does not have the same impact as a sincere tear from a scholar whose heart Allah has filled with reverence. The scholars have said: "Do not take knowledge from a journalist (one who learns only from books) nor the Qur'an from a copyist (one who learns only from a mushaf)." Therefore, every responsible individual must strive to receive knowledge directly from the mouths of its specialized people, for this is the tradition of the Salaf.
