It was narrated that Safwan bin 'Assal said: "The Messenger of Allah used to command us not to take off our leather socks for three days except in the case of sexual impurity, but not in the case of defecation, urine or sleep (i.e. during travel)."

It was narrated that Shuraih bin Hani' said: "I asked 'Aishah about wiping over the leather socks and she said: 'Go to 'Ali and ask him, for he knows more about that than I do.' So I went to 'Ali and asked him about wiping. He said: 'The Messenger of Allah used to tell us that the resident could wipe for one day and one night, and the traveler could do so for three days.'"

It was narrated that Khuzaimah bin Thabit said: "The Messenger of Allah set a time limit for the traveler of three days, and if the questioner had persisted in asking, he would have made it five (days)."

It was narrated from Khuzaimah bin Thabit that: The Prophet said: "Three days." I think he said, "And three nights during which the traveler may wipe over his leather socks."

It was narrated that Abu Hurairah said: "They said: 'O Messenger of Allah! What about the purification of the leather socks?' He said: 'For the traveler it is three days and nights, and for the resident it is one day and one night.'"

It was narrated from 'Abdur-Rahman bin Abu Bakrah, from his father, that: The Prophet granted a concession to travelers: "If a traveler performed ablution and put on leather socks, then he performed a fresh ablution, he could wipe over the leather socks for three days and nights; the resident could do so for one day and one night."

It was narrated from Ubayy bin 'Imarah, in whose house the Messenger of Allah performed prayer facing both prayer direction, that : He said to the Messenger of Allah: "Can I wipe over my leather socks?" He said: "Yes." He said: "For one day?" He said: "For two days?" He said: "For three?" And so on, until the number reached seven. He (the Prophet) said: "For as long as you see fit."
