Fasting person masturbating

Question: I used to masturbate during the daytime in Ramadaan when I was fourteen and fifteen years old. I do not remember how many days I did that. At that time I was not aware that this is Haraam (prohibited); whether in Ramadaan or at any other time. I even did not realize that this is what is known as the secret habit (masturbation). I would then perform Wudoo’ (ablution) and offer Salaah (Prayer) without Ghusl (full ritual bath) following major ritual impurity. What is the religious ruling on my Salaah and Sawm (Fasting)? Do I have to repeat them, taking into consideration that I do not know how many days that I committed this act? What should I do?

Answer: First, practicing masturbation is Haraam (prohibited) and it is even more sinful during the day in Ramadaan. Second, it is obligatory to make up for the days on which you broke your Sawm because masturbation invalidates Sawm. You should try to estimate how many days this occurred. Third, it is also obligatory to pay Kaffaarah (expiation) which is giving a needy person half a Sa‘ (1 Sa‘ = 2.172 kg) of wheat and the like of the staple food of your area for each day that you missed if you delay making up for it until the next Ramadaan arrives… read more here.
