Does intentional masturbation, with the emission of semen, during the daytime in Ramadan, invalidate the fast, knowing that it does not weaken the body and expels desire?

Masturbation is forbidden and invalidates the fast if semen is ejaculated. This is the view of the majority of scholars, such as Ibn Qudamah and the four Imams. Ibn 'Uthaymeen holds that it breaks the fast for two reasons: The first is that masturbation is a desire, and Allah Almighty said concerning the fasting person, "He leaves his food, drink, and desires for My sake," and semen is called a desire. The second reason is by analogy with vomiting and cupping, both of which weaken the body, and the emission of semen also weakens the body.
