What are the conditions for wiping over socks, and is it permissible to wipe over them continuously?

The limited time for wiping over socks is three days and their nights for the traveler, and one day and one night for the resident, as was reported from Ali ibn Abi Talib, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, made it so. This is the madhhab of the majority of scholars. If the period ends, one must remove them and wash the feet, then it is permissible to wear them and wipe over them again for the same period.
