Try to restrain your yawn with your hand

This hadith teaches us that when we yawn, we should use our hands to cover our mouths and not let out a loud sound. It is believed that when we do this, we are preventing Satan from entering into us. This hadith also encourages us to be mindful and aware in all situations, even something as simple as a yawn. We must remember that Allah is always watching over us and He knows what is best for us. Therefore, by restraining ourselves from making loud noises or gestures such as a big yawn, we are showing respect for Allah's commands and teachings.
