She loves Islamic nasheeds and they take up a lot of her time

Firstly: 

Songs which are accompanied by musical instruments or which
contain words of love or provoke desire, are undoubtedly haraam, because of
a great deal of evidence to that effect, which you will find in the answers
to questions no. 5000 and
20406. 

So we praise Allaah for having enabled you to give up
listening to songs and turned your heart away from them. 

Secondly: 

There is nothing wrong with listening to Islamic nasheeds
which contain words of wisdom, exhortation, encouragement to do good, and
promotion of noble attitudes, so long as there are no musical instruments
and the voices do not provoke fitnah or incite one to do haraam deeds, and
so long as one does not listen to them a great deal. 

The Standing Committee issued a detailed fatwa concerning the
ruling on Islamic nasheeds, which states the following: 

You have spoken the truth concerning the prohibition on songs
as they exist nowadays, because they include immoral and indecent words, and
they include things in which there is nothing good. Indeed, they are full of
idle talk and provocation of desire, sexual urges and promiscuity, and
softening of the voice in such a way that it tempts the listener to evil.
May Allaah help us and you to do that which pleases Him. 

It is permissible, as an alternative to these songs, for you
to listen to Islamic nasheeds which include wisdom, exhortation and words
that promote enthusiasm and protective jealousy for Islam, and stir up
Islamic feelings, and put one off evil and the things that lead to it, to
motivate the one who “sings” the nasheeds and the one who listens to them to
obey Allaah and deter them from sin and transgressing the sacred limits of
Allaah, and encourage them to live life within the framework of sharee’ah
and to strive in jihad for His sake. But he should not regard that as a
“wird” that he must adhere to, or a habit in which he engages on a continual
basis, rather it should be something that he listens to from time to time on
appropriate occasions when there is a need for it, such as at weddings, when
travelling for jihad, and so on, or when he is feeling listless and needs
something to revive his spirits and encourage him to do good, or when he
feels inclined towards evil so he listens to it to deter himself from it. 

Even better than that is committing oneself to reasing a
portion of Qur’aan on a daily basis, or a wird of dhikrs that are narrated
from the Prophet (peace and blessings of Allaah be upon him). That is
purer for his soul and is more effective in bringing comfort to the heart.
Allaah says (interpretation of the meaning): 

“Allaah has sent down the Best Statement, a Book (this
Qur’aan), its parts resembling each other (in goodness and truth) (and)
oft‑repeated. The skins of those who fear their Lord shiver from it (when
they recite it or hear it). Then their skin and their heart soften to the
remembrance of Allaah. That is the Guidance of Allaah. He guides therewith
whom He wills; and whomever Allaah sends astray, for him there is no guide”

[al-Zumar 39:23]

“Those who believed (in the Oneness of Allaah — Islamic
Monotheism), and whose hearts find rest in the remembrance of Allaah verily,
in the remembrance of Allaah do hearts find rest.

29. Those who believed (in the Oneness of Allaah — Islamic
Monotheism), and work righteousness, Tûbâ (all kinds of happiness or name of
a tree in Paradise) is for them and a beautiful place of (final) return”

[al-Ra’d 13:28, 29]

The way of the Sahaabah (may Allaah be pleased with them) was
to pay particular attention to the Qur’aan and Sunnah, memorizing it,
studying it and acting upon it. Along with that they also had nasheeds and
chants which they would recite, such as when digging the ditch and building
mosques, and when travelling for jihad, and on other such occasions, without
making that their habit or focusing all their attention on it; it was simply
something with which they would relax occasionally or stir their emotions. 
 

With regard to the tabl drum and other musical instruments,
it is not permissible to use them with these nasheeds, because the Prophet
(peace and blessings of Allaah be upon him) and his companions (may
Allaah be pleased with them) did not do that. 

Allaah is the Guide to the Straight Path. May Allaah send
blessings and peace upon our Prophet Muhammad and upon his family and
companions. End quote from Fataawa Islamiyyah, 4/532 

Thirdly: 

You should remember
Allaah a great deal (dhikr) and read Qur’aan; set yourself a daily wird to
memorize and review. Also keep yourself busy listening to some lessons and
lectures, because this is the best means of reducing the amount of nasheed
you listen to, and making use of your time with something that is beneficial
and useful. 

It is very unfortunate that the one who listens to nasheed a
great deal finds it difficult to read Qur’aan or even to listen to it; this
is something harmful which should not be taken lightly. Even if the harm is
only causing him to miss out on a great deal of reward, that is should be
sufficient deterrent for the people of faith from becoming attached to
nasheeds and always listening to them. 

It is well known that if a believer spends an hour reading
Qur’aan, thousands of hasanaat will be recorded for him, because the Prophet
(peace and blessings of Allaah be upon him) said: “Whoever reads one
letter of the Book of Allaah will have one hasanah for that, and a hasanah
brings a tenfold reward. I do not say that alif-laam-meem is a letter,
rather alif is a letter, laam is a letter, meem is a letter.” Narrated by
al-Tirmidhi, 2910; classed as saheeh by al-Albaani in Saheeh al-Tirmidhi. 

One hour is sufficient
to read twenty pages of Qur’aan, in which there are no less than nine
thousand letters. 

How can a person let listening to nasheeds distract him from
listening to the Book of Allaah and reciting it? 

Strive to reduce the amount of time you spend listening to
these nasheeds as much as you can, so that you only listen to them during
weddings, Eid and so on, and make the best use of your time so that you may
rise in status. Soon, by Allaah’s leave, you will find delight in reading
Qur’aan, and the joy of worship and the sweetness of faith, with the words
of the Most Merciful. 

We ask Allaah to help us and you to do that which He loves
and which pleases Him. 

And Allaah knows best.
