Punishment for Masturbation in Islam
Question

I would like to know. Due to masturbation I broke my hymen. Does this makes me a zaniya. Do i have to be punished with hundred lashes or is there any other punishment for this in our religion. And if there is please let me know and I also want to know can I marry a chaste person after indulging in masturbation so many times. Please answer in accordance with Quran and Sunnah.
Praise be to Allah.Is masturbation prohibited?
The masturbation is prohibited , as we have explained in the answer to question no. 329 . You have to repent from this action and give it up , and regret what you have done , and resolve not to go back to it. 
There are many punishments for the sinner in this world, let alone the punishment that he deserves in the Hereafter. We have already mentioned some of these punishments in the answer to question no. 23425 . 
So hasten to repent sincerely before you are no longer able to do so, and before you feel regret at the time when regret will be to no avail. 
If Allah honours you by enabling you to repent, you will be forgiven for this sin, and it will be as if it never happened. The Prophet (peace and blessings of Allah be upon him) said: “The one who repents is like the one who did not sin.” (Narrated by Ibn Majah; classed as good by Al-Albani in Sahih Ibn Majah, 3427) 
Punishment for Masturbation in Islam
Breaking the hymen as a result of masturbation is not Zina, and no Hadd (fixed prescribed punishment) or expiation is required. 
Shaykh Al-Islam Ibn Taymiyah (may Allah have mercy on him) was asked about masturbation and he replied: 
With regard to masturbation, the basic ruling is that it is prohibited according to the majority of scholars, and the one who does it should be given a Ta`zir punishment (punishments that are not fixed in Islam and are decided by the ruler), but it is not like Zina. And Allah knows best.” (Al-Fatawa Al-Kubra, 3/439) 
If it is obvious that the hymen has been broken as a result of masturbation, then you have to tell your fiancé what happened to you, without giving any details that may cause you embarrassment. It is sufficient for him to know that this happened without any fornication, because the hymen may be broken because of exercise, being beaten, falling or being sick. 
You will never be exposed if you repent to Allah and are sincere in your repentance, for Allah is the Concealer and loves concealment.
