Is it permissible for a man to sit with his fiancée?

Question:
He says: Honorable Shaykh, may Allah grant you success. A man proposed to a woman in the presence of her mahram (a relative one may not marry), and they agreed that the marriage would take place after a year. Is it permissible for them to repeat their meetings before the marriage, or does this fall under free mixing of men and women?

Answer:
If he does not remain alone with her, and she is wearing hijab (the covering prescribed for women), there is nothing wrong with him sitting with them, provided she is covered and they are not freely mixing. She should not be close to him, and he should not be alone with her. Even if he has not proposed to her, men and women may sit together, but with the women separated from the men and the women covered from the men. Yes.
