Should you suppress a yawn with your right or left hand during salah?

So the Prophet ﷺ said in Sahih Muslim that yawning is from Shaytan. So you should try and suppress yawning, try and avoid it. And in another hadith collected by Abu Dawud The Prophet ﷺ said that you should cover your mouth if you are yawning. So yes, use your left hand to cover your mouth whenever you're going to yawn.
