Is the woman who is divorced after consummation of the marriage entitled to maintenance?

Firstly: 

If a man divorces his wife thrice in one go, such as if he
says “You are divorced three times” or “you are thrice divorced” or he says
it in separate words such as saying “You are divorced, divorced, divorced”,
then it counts as one divorce according to the more correct opinion, and he
may take her back so long as she is still within the ‘iddah period. Once the
‘iddah period has ended he cannot go back to her without a new marriage
contract. 

Secondly: 

The revocably divorced woman (i.e., first or second talaaq)
is entitled to maintenance during her ‘iddah, and it is not permissible to
make her leave the house, because of the words of Allaah (interpretation of
the meaning):

“And turn them not out of their (husband’s) homes nor
shall they (themselves) leave, except in case they are guilty of some open
illegal sexual intercourse. And those are the set limits of Allaah. And
whosoever transgresses the set limits of Allaah, then indeed he has wronged
himself. You (the one who divorces his wife) know not it may be that Allaah
will afterward bring some new thing to pass (i.e. to return her back to you
if that was the first or second divorce)”

[al-Talaaq 65:1].

Based on this, you are entitled to request the maintenance
that your father spent on you during your ‘iddah, if what your husband gave
you was not enough, and you can refer the matter to the sharee’ah court and
make a claim there. If there is no sharee’ah court, and it is not possible
to take your rights by advising your husband or through the intervention of
good people, it is permissible to refer the matter to the civil courts, even
though it is not proper to refer for judgement to man-made laws, but do not
take more than you are entitled to, even if that is awarded to you by the
courts. 

Secondly: 

Allaah says (interpretation of the meaning):

“And for divorced women, maintenance (should be provided)
on reasonable (scale). This is a duty on Al‑Muttaqoon (the pious)”

[al-Baqarah 2:241]

This maintenance is obligatory in the case of a woman who is
divorced before consummation, if she did not have a specified mahr at the
time of the marriage contract, because Allaah says (interpretation of the
meaning):

“There is no sin on you, if you divorce women while yet
you have not touched (had sexual relation with) them, nor appointed unto
them their Mahr (bridal-money given by the husband to his wife at the time
of marriage). But bestow on them (a suitable gift), the rich according to
his means, and the poor according to his means, a gift of reasonable amount
is a duty on the doers of good”

[al-Baqarah 2:236]. 

But if the divorce came after consummation, then maintenance
is not obligatory according to the majority of fuqaha’, rather it is
mustahabb. 

Shaykh al-Islam Ibn Taymiyah (may Allaah have mercy on him)
was of the view that it is obligatory for all divorced women. 

Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) said:
Shaykh al-Islam Ibn Taymiyah (may Allaah have mercy on him) said:
Maintenance must be given to every divorced women, even after consummation.
And he quoted as evidence for that the verse in which Allaah says
(interpretation of the meaning):

“And for divorced women, maintenance (should be provided)
on reasonable (scale). This is a duty on Al‑Muttaqoon (the pious)”

[al-Baqarah 2:241]

“Divorced women” is general in meaning, and the entitlement
is confirmed by the word “duty” [haqqan]. This is further confirmed by the
words “on the pious”. This indicates that doing this is part of piety or
fearing Allaah (taqwa), and fearing Allaah is obligatory. What the Shaykh
[Ibn Taymiyah] said is a very strong argument if the marriage has lasted a
long time, but if the man divorces her within a short period, then in that
case we say: 

Firstly: the woman’s relationship with the man has lasted
only a short time

Secondly: The mahr she was given is still with her, because
it was only given to her recently.  

But if the marriage lasted for a year, or two years, or a few
months, then in that case what Shaykh al-Islam (may Allaah have mercy on
him) said is sound. This is a moderate view that falls in between two others
which say that it is either mustahabb in all cases or obligatory in all
cases. This is the correct view. End quote from al-Sharh al-Mumti’
(12/308). 

Maintenance depends on the husband’s situation, whether he is
rich and well off or poor and hard up. Allaah says (interpretation of the
meaning):

“But bestow on them (a suitable gift), the rich according
to his means, and the poor according to his means”

[al-Baqarah 2:236]. 

There is no specific, set amount in this case. 

If a man divorces his wife, he should offer some consolation
by giving her some money. 

As for referring the claim to the husband’s relatives, we do
not think that this will achieve anything for you. Refer their matter to
Allaah, for He will requite each person for what he did. 

You do not know what is best for you. Perhaps Allaah will
bring you something good, as Allaah says (interpretation of the meaning):

“it may be that you dislike a thing which is good for you
and that you like a thing which is bad for you. Allaah knows but you do not
know”

[al-Baqarah 2:216]

Turn to Allaah and cling to Him, and delegate your affairs to
Him, and do a lot of acts of worship. Allaah will not let His righteous
slaves down. 

We ask Allaah to heal you, grant you well being and decree
good for you. 

And Allaah knows best.
