The Ruling on Forgetting Rinsing the Mouth and Nose in the Full Ritual Bath

The questioner:
May Allah reward you, Honorable Shaykh. I often perform the full ritual bath without performing the ablution, and I forget to rinse my mouth and nose. Sometimes I remember after I have put on my clothes, so I rinse my mouth and nose. Other times I forget and do not remember, and I pray several obligatory prayers with this bath. What is obligatory for me?

The Shaykh:
This is waswas (whispers of Satan). It appears to be waswas. I do not think anyone performs the ablution without rinsing the nose or mouth, but it appears to be waswas. What is your news?

The presenter:
Let us praise Allah.

The Shaykh:
No, but focus on this in the future. Focus on this in the future. As for what has passed, it appears that it is valid. Yes.

The questioner:
If he forgets it in the full ritual bath, he is required to repeat it.

The Shaykh:
He rinses his mouth and nose and it is sufficient. Yes.

The presenter:
May Allah forgive you.
