The ruling on the fast of one who intends to fast while in a state of major ritual impurity

Question:
The questioner says: I was in a state of major ritual impurity on this day, and I remembered that I was in a state of major ritual impurity, so I performed the full ritual bath before the call to the midday prayer. Is my fast valid?

Answer:
Yes, your fast is valid. It is permissible for a person to intend to fast while in a state of major ritual impurity and then perform the full ritual bath afterwards. This is something that happened to the Prophet (peace and blessings be upon him). The dawn prayer would overtake him (peace and blessings be upon him) while he was in a state of major ritual impurity, then he would fast, and then he would perform the full ritual bath (peace and blessings be upon him) afterwards. Yes.
