She got to know a man through the Internet and she wants to carry on talking to him and getting to know him because she wants to marry him

Ascertaining that a suitor is
qualified in terms of character and religious commitment is one of the two
foundations of a successful marriage; the other foundation is emotional
compatibility and inclination of the heart. The first foundation is the more
important, because character and religious commitment form the basis of
every successful relationship and happy household, even if it is devoid of
complete love and emotional harmony. 

Hence attention should be paid
to this foundation as much as is possible, and help should be sought from
Allah, may He be glorified and exalted, to choose one who is religiously
committed and of good character. We have previously stated in fatwa no.
105728 some of the means that will help to achieve
this aim. 

With regard to conversations
between a man and a woman who are not mahrams via chat programs, the basic
principle concerning this is that it is not allowed, because it opens the
door to evil and fitnah. How often have such conversations brought evil and
calamity to the participants, and even caused them to become infatuated, and
has led to some of them committing immoral actions and sins. The Shaytaan
may cause each party to see in the other characteristics that cause them to
become infatuated, which has a negative impact on their worldly and
religious affairs. 

Islam closes all the doors that
may lead to fitnah. Hence it forbids speaking in a soft voice, shaking hands
with a non-mahram woman, looking at her and being alone with her. These
private conversations are one of the causes of fitnah, as is well known. 

Shaykh Ibn Jibreen (may Allah
preserve him) was asked: What is the ruling on correspondence between young
men and women, so long as this correspondence is free of immoral matters,
infatuation and so on? 

He replied: 

It is not permissible for any
man to correspond with a woman who is not his mahram, because of the fitnah
to which that leads. The man may think that there is no fitnah, but the
Shaytaan will keep trying to tempt him and tempt her. The Prophet (blessings
and peace of Allah be upon him) instructed the one who hears of the Dajjaal
to keep far away from him, and he said that a man may come to him as a
believer, but the Dajjaal will keep trying to influence him until he
confuses him. 

Correspondence between young men
and young women is a great fitnah and poses a grave danger; it should be
strictly avoided, even if the questioner says that he is not infatuated with
her.

End quote from Fataawa al-Mar’ah,
compiled by Muhammad al-Musnad, p. 96 

Undoubtedly talking via chat has
a greater impact and poses a greater danger than corresponding by mail. So
fear Allah and refrain from talking to this man. That is safer for your
religious commitment and is purer for your heart. You should understand that
marriage to a righteous man is a blessing from Allah, may He be exalted, and
a blessing cannot be attained by means of sin. 

If this man wants to marry you,
then let him approach the matter properly and correspond with your guardian
in order to propose marriage to you. Then after that, the matter of
ascertaining his religious commitment and character may be done by means
that are Islamically acceptable, which we have explained in the fatwa
referred to above. 

Moreover, this matter is in fact
the responsibility of the guardian. One of his most important roles is being
in charge of the marriage contract. He should examine the situation of the
suitor and find out about him to see whether he is compatible, qualified, 
and able to fulfill the duties of marriage. The woman is not able to decide
about these matters in an objective and correct manner. 

If you can inform him of what he
must do before he comes to propose marriage to you, then when he has the
financial means and is compatible, he must approach the matter properly, and
he should approach your father and get to know your family. 

And Allah knows best.
