The Proof Against Masturbation

Question :

What is the ruling regarding the practice of masturba- tion, and if it is unlawful, please provide proof from the Qur'an and the Sunnah?

Answer:

The practice of masturbation is forbidden in Islam; its harms are great and many. Its prohibition is proven by the saying of Allah Almighty in Surat Al-Mu'minun:
"But whoever seeks beyond that, then those are the transgres- sors."

Meaning, whoever seeks to satisfy his lust with someone other than his wife and (lawful) slave, he is from the transgressors. Shaykh Muhammad Amin Ash-Shinqiti mentioned this proof in his Tafsir entitled, Adhwa' Al-Bayan.

Some narrations mention that some people would keep a rope that they used to tie around their sexual organ.

Some scholars, however, have deemed masturbation permissible for someone when he is afraid that he will fornicate, provided that person feels that there is no other way of escaping from the greater evil. Nevertheless, such a person should first attempt to get married; thereafter, he should try to fast, for it is a shield against desires. And Allah Almighty knows best.
