Yawning and Seeking Refuge from Satan

Question:
And other than the Shaykh, may Allah grant you success, is yawning a provocation from Satan, such that the one yawning should seek 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 respond to this sneeze because it is a blessing from Allah. As for yawning, it is from Satan, and therefore yawning is forbidden. If one is overcome by yawning, let him place his hand over his mouth.
And he should not suppress it as much as he can, nor raise his voice in the exchange; he should suppress it as much as he can, because it is from Satan and it indicates laziness and drowsiness. So he resists the exchange; whatever happens, he prevents it, he prevents it. And whatever happens, he prevents it, at least he lowers it. He places his cup or his sleeve over his mouth, and he does not leave it open. As for saying, "We seek refuge in Allah from Satan the accursed," this is not it, O Allah, and it is not a precaution.
