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. (Using translation from Abū Dāʾūd 4139)
"إِذَا انْتعَل أحدُكم فْليبدأ باليُمنى وإذا خلعَ فليبدأُ بالشّمالِ- لتكن اليمينُ أوّلَهما تنتعلُ وآخَرهما تنزعُ".
