Is it permissible for a suitor to call his fiancée on the phone?

Question:
Does a person ask if, when he proposes to a woman, is it permissible for him to speak with her on the phone? As for speech that involves asking and answering about matters that concern the spouses or the suitors, in which there is benefit for the suitors,

Answer:
there is nothing wrong with that. As for speech that contains flirtation or speech that is submissive in tone, this is not permissible, because she has not yet become his wife; she is a non-mahram to him, and he is a non-mahram to her. So he does not speak to her with loose speech that leads to desire or concerns these matters. This is not permissible. Flirtation or speech that leads to sexual intercourse is forbidden and not permissible, because she is not his wife merely by virtue of the proposal.
