One who prays while forgetting that he is in a state of major ritual impurity

The questioner:
Something. And if he is in a state of major ritual impurity and knows about it.

The Shaykh:
So when the time for the 'Asr prayer came, he became aware of it, so the prayer was repeated for him, and the Fajr and Zuhr prayers were invalidated. Yes. If he prayed Fajr and Zuhr while he had not performed the full ritual bath, forgetting that he was in a state of major ritual impurity, then he must perform the full ritual bath when he remembers and repeat the prayers he performed. Because his prayer is not valid while he is in a state of major ritual impurity. Forgetting does not exempt him from performing the full ritual bath; forgetting does not remove an obligatory duty, it only removes the sin. It removes the sin, but it does not remove the obligatory duty through forgetting.
