Her mother is rejecting the fiancé because there was no prior relationship or dating

Question

Praise be to Allah.

Firstly:

We congratulate our sister on embracing Islam and we ask
Allah to bless you with the guidance of your family and loved ones, and to
help you to obey Him and seek His pleasure, and bless you with a righteous
husband and righteous offspring.

Secondly:

Marriage in Islam is based on the proposal then the marriage
contract. For the purposes of the proposal the man is allowed to see the
woman and she is allowed to see him, so that the marriage will be based on
clarity. That should be accompanied by asking about the man in order to find
out about his character, religious commitment and condition, and the
situation of his family. If he is good, then the basic principle is that he
should be accepted, because the Prophet (blessings and peace of Allah be
upon him) said: “If there comes to you one whose
religious commitment and attitude pleases you, then marry [your
female relative who is under your care]
to him, for if you do not do that, there will be tribulation on earth and
much corruption.”

Narrated by at-Tirmidhi (1084)
from the hadeeth of Abu Hurayrah. Classed as hasan by al-Albaani in
Saheeh at-Tirmidhi.

The fiancé is still a stranger to
the woman, so it is not permissible for him to be alone with her, or to
shake hands with her, or to look at her apart from looking in order to
decide whether to go ahead with the proposal.

From this you will understand that
Islam does not permit a relationship between a man and a woman who is not
his mahram, even if that is for the purpose of marriage. This relationship
is not permissible either before or after the proposal. But if there is a
need to sit with the one who is proposing once or more in order to find out
about his situation or to make arrangements for the marriage contract, there
is nothing wrong with that so long as a mahram is present, and the woman
wears proper hijab, and she treats him as as a man who is a non-mahram.

Thirdly:

If your mother does not approve of
the man for the reasons mentioned, which is that she thinks it is essential
for there to be dating and a relationship and getting to know one another
before proposing marriage, you do not have to obey her in her rejection of
this man, because she is calling you to do something that is not permissible
in Islam, and there is no obedience to any created being if it involves
disobedience to the Creator. In that case you have to explain to her the
ruling on these relationships and try to convince her of the marriage by
telling her about some of the good qualities of the man after you have asked
about him and found out about him.

If her rejection is for an
acceptable reason, whether it has to do with religious or worldly matters,
such as any shortcoming in his wealth or appearance, or something bad in his
family and so on, then it is better to obey your moher.

If there is no acceptable reason
for her refusal, then you do not have to obey her, but you should strive to
please her and make her happy because of the great rights to kind treatment
and respect that the mother has.

Fourthly:

In order for the marriage contract
to be valid it must done by the woman’s guardian, because the Prophet
(blessings and peace of Allah be upon him) said:
“There is no marriage except with a guardian.” Narrated by
Abu Dawood, 2085; al-Tirmidhi, 1101; Ibn Maajah, 1881, from Abu Moosa
al-Ash‘ari. Classed as saheeh by al-Albaani in Saheeh at-Tirmidhi.

The woman’s guardian is her father, then his father (i.e.,
paternal grandfather), then her son, then his son (i.e., grandson, if she
has a son), then her brother through her father and mother, then her brother
through her father only, then their sons, then her paternal uncles, then
their sons, then the ruler. See: al-Mughni, 9/355

If the woman does not have any
Muslim guardian from this list, the Muslim judge (qaadi) should do the
marriage contract for her. If there is no Muslim judge, then a man of status
among the Muslims, such as the Imam of the Islamic Centre, should do the
marriage contract for her.

We ask Allah, may He be exalted,
to help and guide you.

And Allah knows best.
