Malik bin Mghwl مالك بن مغول · The Book of Purification

"I asked Safwan bin 'Assal about wiping over the Khuffs, and he said: 'The Messenger of Allah (ﷺ) used to tell us, when we were travelling, to wipe over our Khuffs and not take them off for three nights in the event of defecating, urinating or sleeping; only in the case of Janabah.'"

"I saw the Prophet (ﷺ) in Al-Batha'. Bilal brought out the water left over from his Wudu' and the people rushed toward it and I got some of it. Then a short spear was planted in the ground and he led the people in prayer, while donkeys, dogs and women were passing in front of him."
