What is the ruling on the emission of prostatic fluid (madhy) due to a dream of driving a car at high speed, then the matter turned into masturbation by hand after waking up and going back to sleep with the intention of ejaculating semen? Does this invalidate the fast and require making up for it?

If you discharge semen while awake and through your own action, this is masturbation. Masturbation is the expulsion of semen without intercourse through some means, and it can occur from both men and women. It invalidates the fast if it results in the emission of semen. One must make up the day on which intentional masturbation occurred with semen emission, and repent to Allah. However, if semen is not emitted, the fast is not invalidated.
