Be mindful of your actions and maintain cleanliness in public places such as mosques; Spit only on your left side or under your left foot; Respect others by being aware of your surroundings and not doing anything that would cause discomfort for them.

This hadith is about the etiquette of spitting according to the Prophet Muhammad ﷺ. He saw sputum on the wall of a mosque and scraped it off with gravel. He then forbade people from spitting in front or on their right side, but allowed them to spit on their left side or under their left foot. This hadith teaches us that we should be mindful of our actions and maintain cleanliness in public places such as mosques. We should also be aware of our surroundings and not do anything that would cause discomfort for others, such as spitting in an inappropriate place.
