Try to restrain your yawns and do not say "Ha, Ha".

This hadith is about the etiquette of yawning. It teaches us that Allah likes sneezing but dislikes yawning, and when we yawn we should try to restrain it as much as possible. We should not say "Ha, Ha" when we yawn because this is from the devil who laughs at us. This hadith encourages us to be mindful of our actions and to practice good manners in all situations. It also reminds us that even small things like a simple yawn can have spiritual implications if done incorrectly or without proper etiquette.
