Musannaf Ibn Abi Shaybah

Hazrat Imran bin Muslim says that Nabatah Jufi used to be fearless among us in front of Hazrat Umar. We said to Nabatah Jufi, "Ask Hazrat Umar about the duration of wiping over the leather socks." When Hazrat Umar was asked, he prescribed three days for the traveler and one day and one night for the resident.
