Logic is not a tool for religion...!
馃憞
From the hadith of Ali ibn abi thalib ra
If religion is by logic alone, then the lower part of khuf more deserved in the swab from the top. but really I have seen the Messenger of Allah wipe the top of his khuf.
If with the logic of ablution should be the bottom of the wipe because the bottom is definitely dirtier than the top.
