A man performed the full ritual bath to remove major ritual impurity, intending to also perform the ablution for prayer, and during the bath his hand touched his private part. Does he have to repeat it?

Question:
He says: Honorable Shaykh, may Allah grant you success. If a man performs the full ritual bath to remove major ritual impurity, intending to perform both the minor and major purification, and during the bath he breaks his state of purity or his hand touches his private part, does he complete his bath? And is it permissible for him to pray without performing the ablution?

Answer:
No, the intention must be from the beginning. If he intends both states of purity, the intention must be from the very start. If the ablution is broken during the bath, the intention for the ablution is invalidated. He must restart the ablution from the beginning, or restart the full ritual bath for both purifications from the beginning.
