What remains from investigating this issue is the timing of wiping the head. Is there a virtue in repeating it or not? Some people say that there is no virtue in it, and among them are those who say that there is virtue in it. This is desirable in all acts of ablution in all its parts, regardless of the fact that it is strengthened in some parts and weakened. In some parts, I mean repetition, and there is no dispute about the obligation of one part if it covers the part.
