Ash'ath bin Abi al-Ash'atha أشعث بن أبي الشعثاء · Clothing (Kitab Al-Libas)

The Messenger of Allah (ﷺ) as saying: When one of you puts on sandals, he should put on his right one first, and when he takes them off, he should take off the left one first ; so that the right one should be the first to be put on and the last to be taken off.
