Take precautions when engaging in physical activities and be mindful of your actions so as not to harm others or yourself.

This hadith is about the prohibition of throwing pebbles in sport by the Prophet Muhammad, peace be upon him. He warned that such an activity could lead to serious injury, such as putting out an eye or breaking a tooth. The Prophet was concerned for people's safety and wanted to ensure that no one would get hurt while playing games or engaging in any other activities. He taught us that we should always take precautions when engaging in any kind of physical activity and be mindful of our actions so as not to harm others or ourselves.
