Masturbation and Pornography

Q:

1. Is masturbation allowed in Islam?

2. I have read that masturbation causes memory and eyes to become weak etc. Is this true?

Q: The people who watch pornography and also watch porn videos, is this equal to Zina?

Q: Today I had a lucid dream (knowing that you are dreaming) then I masturbated consciusly. Is that permissible?

Q: I am 15 years old girl. Alhamdulliah I wear a hijab whenever I go out. My problem is that I masturbate, and I feel extremely guilty about it because I know it's wrong but I still can't stop myself. Whenever I go out even though i'm covered I still want the boys to look at me (I know it's very wrong). Whenever I stand in front of the mirror I think that I'm so pretty. I don't know I really want to get close to Allah but I fail every time. I don't feel like praying, I am always tired. I don't know if it's right to say but I hate myself, I hate the fact that I'm alive. I am nothing but a shame. I really want to get close to Allah. I am so scared every time that what if I die suddenly, Allah is never going to forgive me. I don't even know how to explain all my feelings to you. I hope you understand what I'm trying to say because it's impossible to express my feelings.

Q: If a boy who has not reached the age of maturity, but when he masturbates he ejaculates semen. Is he getting the sin of masturbating?

Q: I am a 15 year old Muslim boy. My question is that is masturbation also not allowed for teenagers who are not married. With all due respect I do not go against Quran and Hadith but this topic isn't mentioned in it specifically. I mean if masturbation stops us from zina and watching porn before marriage shouldn't it be allowed for the unmarried?

Q: If a girl masturbates about her future husband is it haraam? If yes then how could one repent?

Q: The act of masturbation is defined as rubbing ones private parts to reach climax and this is not allowed in Islam. Now my question is, is it wrong if a person without touching his privates reaches climax, for example, bouncing on ones bed facing towards the roof with the intention of climaxing yet not touching the genitals. Would this be termed as 'masturbation' and is it wrong Islamically?

Q: I'd like to know regarding the harms of mastabation and watching pornography. Please kindly provide Ahadith of the Prophet صلّى الله عليه وسلم.
