What is the reconciliation between the noble Prophetic Hadith: "If one of you yawns, let him suppress it as much as he can, for if one of you yawns, Satan laughs at him," and the scientific evidence that yawning is beneficial for maintaining brain temperature and the body's need for oxygen?

Scholars unanimously agree that definite revelation does not contradict definite reason, and a proven scientific fact cannot contradict a definite legal text.

Yawning is a controversial phenomenon. Some theories suggest it aims to bring in more oxygen or expel carbon dioxide, but these hypotheses have not been scientifically proven. Yawning occurs in fetuses who do not breathe, and increasing oxygen or reducing carbon dioxide does not decrease yawning.

What makes yawning even stranger is its "contagious" nature, spreading among people.

Physicians have mentioned several harms associated with yawning: - The entry of germs and insects into the body because the mouth is not equipped to filter air like the nose. - Causing disgust to the beholder when the mouth is opened and bad breath appears. - The possibility of temporomandibular joint dislocation due to sudden jaw movement.

The prophetic hadiths that condemn yawning and command its suppression do not negate its potential benefit, but rather clarify what should be done when it occurs.
