Be respectful and mindful when you're inside a place of worship; Be careful with your movements so as not to cause any damage or disruption; Hold onto arrow heads while moving around in mosques; Follow commandments given by Prophet Muhammad .

This hadith is about how one should behave when they are in a mosque. The Prophet Muhammad commanded that no one should move around inside the mosque without holding onto the iron-heads of arrows. This teaches us that we must be respectful and mindful of our behavior when we are inside a place of worship. We must remember to be quiet and not disturb others who are praying or engaging in other religious activities. It also reminds us to be careful with our movements so as not to cause any damage or disruption within a holy place like a mosque.
