Is it obligatory to repeat prayers and fasting after having practiced masturbation in previous periods without knowing its ruling? Is it permissible to delay making up for them due to studying? What is the opinion regarding fatwas that permit masturbation, and what are the cases in which it is permitted?

Whoever experiences a wet dream and semen is discharged must perform ghusl (ritual bath) in order to pray; otherwise, their prayer is invalid. Missed prayers due to the ترك الغسل (neglect of ghusl) must be made up. One should strive to determine their number or make up what ensures certainty of fulfilling one's obligation. As for fasting, it is not necessary to make up if the ignorance was concerning whether a wet dream breaks the fast. Masturbation is forbidden in all circumstances.
