<b>Guidance from the Hadith:</b><br> 1) It establishes that the devil enters one’s body when he yawns and opens his mouth.<br> 2) The Shariah points out the method by which a person can protect himself from the devil while yawning.<br> 3) We should believe in the information told by Allah Almighty and His Messenger, for it is certain, even if we do not see it with our own eyes. This is part of the submission to the divine revelation, which is due upon every Muslim.
