Is a girl's online conversation with a young man, with her parents' knowledge and a sincere intention to marry, considered unlawful (haram)?

The forbidden relationship must be severed immediately, even if it is with the intention of marriage. It is impermissible to converse with him via the internet or otherwise. If the young man is sincere in his intention to marry, he must approach the guardian (wali) and عقد a lawful marriage contract (nikah). The advice necessitates cutting off such relationships due to the corrupting influences they may lead to. Thus, guarding against the whispers of Satan and severing the means through which he infiltrates is essential. If the young man does not approach the guardian, he is like others who exploit these matters to trap unsuspecting women.
