question #1 Sahih al-Bukhari 206, Book 4, Hadith 72 : What is the significance of wiping over socks during ablution in Islamic practice?

My father said, “Once I was in the company of the Prophet (ﷺ) on a journey and I dashed to take off his
Khuffs (socks made from thick fabric or leather). He ordered me to leave them as he had put them
after performing ablution. So he passed wet hands over them.
