A man prayed for years without knowing the obligation of the full ritual bath for major ritual impurity; does he have to repeat the prayers?

The questioner : A man told us that he used to have intercourse with his wife and did not take a full ritual bath for many years. He used to pray during this state of major ritual impurity. Do we oblige him to repeat the prayers?

The Shaykh : What we hold is that if the full ritual bath did not cross his mind and he had not heard of it, he does not have to repeat anything except the prayer he is currently in, if he is in a state of major ritual impurity; he takes the full ritual bath and repeats it. However, if he is a negligent man, it is obligatory for him to repeat every prayer he performed without taking the full ritual bath.

The questioner : Present, Shaykh.

The Shaykh : This is if he remembers, for example, now after the night prayer.
