Rinsing the mouth and nose in the obligatory ritual bath

Question:
He says: Honorable Shaykh, may Allah grant you success. He says: Is it obligatory to rinse the mouth and nose when performing the obligatory ritual bath?

Answer:
Without a doubt, rinsing the mouth and nose are obligatory in the ablution and in the ritual bath, because the mouth and the nose are part of the face. Allah (Mighty and Majestic) said: "So wash your faces," and the inside of the nose and the inside of the mouth are part of the face. So one rinses the mouth, and the Prophet (peace and blessings be upon him) used to rinse his mouth and nose, and he used to command rinsing the mouth and nose in the ablution and in the ritual bath.
