Assalamualikum, brother
Masturbation is
haram (unlawful).
'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.' (Al-Mu'minoon:5-7)
The masturbator is one of those who
‘crave something beyond that.’
It has been reported by Abu Hurrairah (R.A) that Allah's Messenger (P.B.U.H) said :
''A group of people will be gathered on the Day of Judgement with hands pregnant due to practising masturbation''. (Al-Hakim)
Abu Hurrairah (R.A) also reported that Allah's Messenger (P.B.U.H) said Seven have been cursed by Allah (SWT) and he will not look at them on the Day of Judgement. It will be said to them enter the Hell with others: the two who commits homosexuality, the one who has sexual intercourse with an animal, the one who marries the daughter and her mother,
the one who practises masturbation, till they repent sincerely'' (Al-Hakim)
Muslim youth who are unable to marry, namely, that he seeks 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.)"
Thus, we advise not to stay alone and then you should make use of the following
1- Observing fasting, because it bolsters one's faith, preserves chastity, and protects one from evil thoughts.
2- Observing moderation in eating and drinking in order to avoid stimulating your desire.
3- Keeping away from anything that is sexually stimulating, such as pornographic pictures, erotic films and love songs.
4- Choosing good and righteous friends.
5- Keeping yourself busy in worship, Reading Quran and spiritual acts.
6- Interacting with activities of the society in such a way that it keeps you away from thinking about sex.
7- Avoiding gatherings and places that bring men and women physically close to each other.
8- Trying to admire natural things such as flowers and beautiful scenery, which do not stimulate one sexually, instead of admiring girls and women.
