Sayyiduna Abu Hurairah, may Allah be pleased with him, narrates this statement of the Noble Prophet, peace and blessings be upon him: "Indeed, Allah Almighty likes sneezing and dislikes yawning. So when any one of you feels like yawning, he should try his best to restrain it, or else place his hand over his mouth, because when he yawns and says 'Ah', Satan laughs within him (as a result of which this sound comes out)."
