I asked ʿA’ishah: Tell me about a man among the Companions of the Prophet ﷺ whom I can ask about wiping over the khuffain. She said: Go to ‘Ali and ask him, for he stayed close to the Prophet ﷺ. So I went to ‘Ali ؓ and asked him, and he said: The Messenger of Allah ﷺ told us to wipe over our khifaf when we travelled.
