Perform wudhu after touching your private parts.

This hadith teaches us the importance of cleanliness and purity in Islam. It is narrated by Busrah that the Prophet Muhammad (PBUH) said that whoever touches their private parts should perform wudu. This means that one must wash their hands and face with water before performing any prayer or religious activity. This is to ensure that we are clean and pure when engaging in religious activities as it is a sign of respect for Allah SWT. Additionally, this hadith also teaches us about modesty and self-control as it encourages us to be mindful of our actions so as not to do anything inappropriate or impure.
