Narrated Ubai bin ‘Imara (rad): I asked, “O Messenger of Allah, may I wipe over the Khuffain (leather socks)?” The Prophet (ﷺ) replied, “Yes”. I asked, “For one day?” He replied, “For one day”, I again asked, “And for two days?” He replied “For two day s too”. I again asked “And for three days” He replied, “Yes, as long as you wish”.
