Is seeking refuge in Allah prescribed when yawning?

Question:
Honorable Shaykh, may Allah grant you success, is yawning a whispering of Satan, such that the one yawning seeks refuge in Allah from Satan the accursed?

Answer:
The Prophet (peace and blessings be upon him) informed us that sneezing is from Allah (Glorified and Exalted is He), and therefore it is prescribed to say the hamd after sneezing, because it is a blessing from Allah. As for yawning, it is from Satan; yawning is from Satan. Therefore, one is prohibited from yawning. If yawning overcomes him, let him place his hand over his mouth and suppress it as much as he can, not raising his voice with the yawn; he suppresses it as much as he can, because it is from Satan, and it indicates laziness and lethargy. So he resists yawning as much as possible. If he can prevent it, he prevents it; and if he cannot prevent it, he at least softens it, and he places his garment or his sleeve over his mouth, and he does not leave it open. As for saying "I seek refuge in Allah from Satan the accursed," this has not been transmitted.
