Re: Masturbation: Why its haraam?
How can it be "haraam"? There is no punishment for it, and there is no explicit verse that asks you to keep away from it. There is no described punishment for it in hell either.
All that Sadiyah has posted is saying that at the most, it might be makruh. The Quranic verse tells you with what other people you are allowed to have intercourse with. Intercourse requires two people (or more). It gives the boundaries that you can't cross in intercourse. It has nothing to do with stimulating yourself - that's not intercourse.
The idea that masturbation is haraam actually comes from the Judeo-Christian faiths. Especially Christians - they're very much against it. So, we have this bias in our heads that masturbation must be evil.
In fact, you have a hadith that says you must do ablution after stimulating yourself. That tells me, that masturbation is okay. Otherwise where are the hadith that say that the Prophet said you can't do it AT ALL?
If anything, the evidence points to it being Makruh, but allowable if nothing else is working for you.
