Keep mosques clean and tidy; Perform wudu before entering a mosque; Respect places where people come to worship Allah; Scrape off anything unclean from walls or floors in mosques

This hadith is about the importance of cleanliness in mosques. It was narrated by 'Aisha that Allah's Messenger saw some nasal secretions, expectoration or sputum on the wall of the mosque in the direction of Qibla and scraped it off. This shows us how important cleanliness is for a place where people come to worship Allah. We should always keep our mosques clean and tidy so that we can pray with peace and concentration without any distractions. We should also make sure to perform wudu before entering a mosque as this is an essential part of being able to pray properly.
