What is the ruling on a man sitting with a woman during the engagement period in the presence of a mahram and without khalwa (private seclusion)? And is it permissible for a man to teach a woman the Quran without khalwa and with the assurance that there will be no fitna (temptation)?

It is permissible for a suitor to sit with his fiancée if there is a need for it, if temptation is secure, and if a mahram is present. Similarly, it is permissible for a woman to learn the Quran from a man if temptation is secure, if there is no seclusion, and if there is a need for it. However, if temptation is feared, it is not permissible. It is better for a woman to learn the Quran from another woman to block any means to evil.
