Is it permissible to marry a girl whom one got to know and convinced to commit to religious observance via the internet, knowing that online acquaintances are common in society?

A man should avoid inviting women to prevent temptation. He should inquire about the prospective fiancée by asking her family and neighbors about her character and religious commitment. If she is devout and of good character, he should marry her; otherwise, he should look for someone else, unless he strongly believes he can positively influence her after marriage. Illicit relationships between men and non-mahram (definition) women, whether online or elsewhere, must be severed. If he is serious about marriage, he should propose to the girl through her family.
