Plucking part of the eyebrows in order to look beautiful for ones husband

It says in Fataawa al-Shaykh Muhammad ibn Saalih
al-‘Uthaymeen: 

Plucking of women’s eyebrows is not permissible, it is the
namas for which the Messenger of Allaah (peace and blessings of Allaah
be upon him) cursed the one who does it. The naamisah is the one who does it
for someone else and the mutanammisah is the one who asks someone else to do
it for her (as mentioned in the hadeeth). The same applies if a woman does
it for herself. It is haraam and is not permitted. 

Allaah is Wise in what He decrees for His slaves. Some people
are beautiful in appearance and some are not; the entire matter is in the
hand of Allaah. It is essential to be patient and seek reward with Allaah,
and not to transgress His sacred limits for the sake of one’s own whims and
desires. 

What I think is that you should not remove anything from the
eyebrows at all, unless there is hair outside of the line of the eyebrows,
such as if there is a mole from which a hair is growing. This may be removed
because in this case it is removing a kind of fault or deformity, not in
order to look beautiful. And Allaah knows best. 

See Fataawa Manaar al-Islam by Shaykh Ibn ‘Uthaymeen (may
Allaah have mercy on him), vol. 3, p. 832. 

Shaykh Ibn Jibreen said: “It is not
permissible to cut the hair of the eyebrows, or to shave it, reduce it or
pluck it, even with the husband’s approval. This is not the matter of
beauty, rather it is altering the creation of Allaah Who is the Best of
creators. A warning has been narrated against doing that and the one who
does it is cursed; this implies that it is forbidden.
