Is continuity a condition in the full ritual bath, or is it permissible to separate it?

Question:
A questioner says: Is continuity a condition in the full ritual bath, or is it permissible to separate it, such that if one performs the ablution at the beginning of the night with the intention of the full ritual bath, then sleeps and completes the full ritual bath at the end of the night, without repeating the washing of the ablution limbs, please advise us, may Allah reward you?

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. And may the prayers and peace be upon the Messenger of Allah, and upon his family and his Companions.
Continuity between the limbs in the ablution is an obligatory part of the ablution, because the Prophet (peace and blessings be upon him) performed the ablution with continuity between his limbs.
So if one delays washing a limb until the limb before it dries in moderate weather, he must repeat it from the beginning, because the continuity has been missed.
The one who washes his limbs at the beginning of the night and completes it at the end of the night, this is as Allah wills.
How can he sleep? Even if it were the case that continuity is not a condition, not an obligation in the ablution, if that were the case, then the washing of his first limbs is invalidated by the sleep, the washing of his first limbs is invalidated by the sleep, yes.
