during ramadan i have masturbated in the middle of the day i really regret doing that and i know it's a big sin but i want to know should i fast 120 days or just one day and what else should i do ? i hope you can help me
It is sufficient to make up just one day of fasting if the fast is broken due to masturbation. Nothing else is necessary.
