What is the ruling on sponsoring an orphaned girl through a missionary organization that distributes Bibles and teaches Christianity, and is it permissible to send her a message to explain Tawhid to her and then cut off financial aid?

Undoubtedly, sponsoring the girl through a church organization is a serious matter, and it might lead to her Christianization. This situation must be rectified, and another way to provide her assistance should be sought, while maintaining communication with her, reminding her of the tenets of her religion, and wisely warning her against the organization. The sponsorship should not be cut off from her so as not to leave the field open for the organization. This incident alerts Muslims and Islamic organizations to redouble their efforts in spreading the religion, assisting Muslims, and preserving their Islamic identity.
