Must the prayer be repeated if a woman experiences seminal discharge approximately two hours after the prayer?

If the emission of semen was not preceded by a cause before the prayer, then its emission does not affect the performed prayer. However, if the emission of semen was preceded by a cause before the prayer, then whoever performed ghusl (definition) (ritual bath) and prayed, their prayer is valid. But jurists have differed on the obligation of repeating ghusl if semen is emitted a short time after the initial ghusl. The more preponderant opinion is the obligation to repeat ghusl, and this is the madhhab (definition) of Shafi'i and Ahmad. Whereas Malik, Al-Thawri, Abu Yusuf, and Ishaq are of the opinion that ghusl is not obligatory at all. And Abu Hanifa is of the opinion that it is obligatory if one did not urinate before the ghusl. The evidence for the obligation of ghusl is "water from water" and its consideration as an invalidating impurity.
