Answered by Shaykh Faraz Rabbani
Question: Assalam alaykum,
What should do someone who has masturbated during the fast?
Answer: Walaikum assalam,
I pray this finds you in the best of health and spirits.
Masturbation during the fast is even more sinful. It doesn’t invalidate the fast unless it results in ejaculation (orgasm).
If the fast is invalidated through masturbation, two things are required: (1) sincere repentance and (2) making up the invalidated fast. However, expiation (kaffara) is not required.
