What is the ruling on secretly inviting a Hindu woman to Islam—without her family's knowledge—and according to her circumstances, after she has come to believe in God and desires to embrace Islam, but has two conditions: marriage to a Muslim man and her family being psychologically and financially prepared?

It is not permissible for a woman to outwardly manifest disbelief while concealing her Islam, unless she fears a certain harm upon herself. As for merely fearing her parents' anger or their disapproval of her Islam, this is not an excuse. Caution must be exercised to avoid transgressing Allah's limits in dealing with her, and it is preferable that sisters well-versed in Islamic law take charge of inviting her [to Islam] to avoid temptation.
