Sex in Islam, - Masturbation:

The pressing need to relieve himself of sexual tension may drive a
young man to masturbation.
The majority of scholars consider it haram. Imam Malik bases his
judgement on the verse,Those who guard their sexual organs except with
their spouses or those whom their right hands possess, for (with
regard to them) they are without blame. But those who crave something
beyond that are transgressors, (23:5-7) arguing that the masturbator
is one of those who "crave something beyond that."
On the other hand, it is reported that Imam Ahmad Ibn Hanbal regarded
semen as an excretion of the body like other excrete and permitted its
expulsion as blood letting is permitted. Ibn Hazm holds the same view.
However, the Hanbali jurists permit masturbation only under two
conditions: first, the fear of committing fornication or adultery, and
second, not having the means to marry.
Sheikh Yusuf Al-Qaradawi comments inThe Lawful and the Prohibited in Islam:
We are inclined to accept the opinion of Imam Ahmad in a situation in
which there is sexual excitation and danger of committing the haram.
For example, a young man has gone abroad to study or work, thereby
encountering many temptations which he fears he will be unable to
resist, may resort to this method of relieving sexual tension provided
he does not do it excessively or make it into a habit.
Yet better than this is the Prophet's advice to the Muslim youth who
is unable to marry, namely, that he seek help through frequent
fasting, for fasting nurtures will-power, teaches control of desires,
and strengthens the fear of Allah. The Prophet, peace and blessings be
upon him, is reported to have said,"O youth, whoever of you is able to
marry, let him marry, for it spares one looking at what one should
not, or lapsing in adultery. And if he cannot marry, let him observe
fasting, for it is a shield against evil."(Reported by Muslim).
You should make use of the following:
1.Observe fasting, because it bolsters one's faith, preserves
chastity, and protects one from evil thoughts.
2.Observe moderation in eating and drinking in order to avoid
stimulating your desire.
3.Keep away from anything that is sexually stimulating, such as
pornographic pictures, erotic films and love songs.
4.Choose good and righteous friends.
5.Keep yourself busy in worship and spiritual acts.
6.Interact with activities of the society in such away that it keeps
you away from thinking about sex.
7.Avoid gatherings and places that bring men and women physically
close to each other.
8.Avoid sleeping on beds that are so soft that they make one think about sex.
9.Try to admire natural things such as flowers and beautiful scenery,
which do not stimulate one sexually, instead of admiring girls and
women.
10.If you find the previous things useful, then it is forbidden for
you to masturbate. However, if you find that you cannot relieve
yourself except through masturbation, and you fear you may lapse in
adultry if you do not masturbate, then the juristic rule which states
that "the lesser evil is to be suffered in order to fend off the major
one" applies to you, as masturbation is deemed to be the lesser of two
evils in this case.But, we would like to stress that this may be done
only in the case of dire necessity, when all soultions prove to be of
no avail.
May Allah guide you to the right path and help you keep away from sins.
Allah Almighty knows best.
