Cover your mouth when you sneeze so you don't make loud noises in public places.

The hadith narrated by Abu Hurairah states that whenever the Prophet Muhammad (peace be upon him) sneezed, he would cover his mouth with his hand or a piece of cloth in order to suppress the sound. This teaches us that it is important to practice good manners and etiquette when we sneeze, as it is considered rude and impolite to make loud noises in public. It also shows us that even though something may seem small or insignificant, such as covering our mouths when we sneeze, it can still have a great impact on how others perceive us and how they view our character. Furthermore, this hadith serves as an example for all Muslims on how they should conduct themselves in public and private settings alike.
