A person has epilepsy. With epilepsy,you also get silent seizure,that the person goes unconscious for a short period of time. They become completely unaware of their surroundings.
Once this person was reading his Maghrib Salaah with Jamaat in the Masjid. The next day another Musalli told him that he did this in his Salaah.
In the 2nd Rakaat after Tashahud,he just sat and didn’t stand up for the 3rd Rakaat.
When the Imaam,came down for Qadatul Akhirah,his seizure stopped and he completed the Salaah as normal.
He is completely unaware of this occurring.
So based on this: Is his Salaah valid?
