From Sahih Muslim (Hadith 5502):
Jabir. b. Abdullah reported Allah's Messenger (ﷺ) as saying:Do not walk in one sandal and do not wrap the lower garment round your knees and do not eat with your left hand and do not wrap yourself completely leaving no room for the arms (to draw out) and do not place one of your feet upon the other while lying on your back
