Question: A young man says that at some point in the distant past he wronged himself and could not control his sexual desire, and Satan enticed him to have sexual intercourse with an animal. Rather, he used to perform the act of masturbation. He adds that he practiced masturbation while he was observing Sawm (Fast) during the month of Ramadaan. He says that he knows masturbation is forbidden, but he did not know that it renders Sawm invalid. He adds that he would keep observing Sawm by abstaining from food and drink during the day, enduring the hot weather and offering Salaah (Prayer). His question is as follows:
1- Does he have to do anything with regard to Sawm of the days on which he practiced masturbation while observing Sawm? It should be taken into account that he does not know the exact number of those days.
2- Is it obligatory on him to offer a Kaffaarah (expiation) for having sex with the animal?
These are the very words of his question. I would be grateful if Your Eminence could send us a clear and confidential answer to this question as I see him distressed and displeased with what he did. May Allaah protect you as pride for all Muslims.
Answer: This young man has to turn to Allaah in repentance for having sex with the animal and performing the act of masturbation. He should seek Forgiveness of his Lord. Besides, he must make up for the days on which he rendered his Sawm invalid by committing such sins... read more here.
