What is the Shar'i ruling for someone who practiced masturbation during the daytime in Ramadan, does not know the number of days, did not perform Ghusl after practicing it, and prays, and how can he get rid of its addiction?

Masturbation is forbidden and invalidates the fast if ejaculation occurs. It is obligatory to make up the day on which ejaculation occurred, unless the person performing the act was unaware that it invalidates the fast. If you do not know the number of days your fast was invalidated, you must estimate them and make up what you believe will clear your conscience. Similarly, you must repeat the prayers you performed while in a state of major ritual impurity (janabah). If you do not know their number, then make up what you believe will clear your conscience.
