Properly dispose off waste according to gender-specific instructions given by Prophet Muhammad .

The hadith narrated by Umm Kurz teaches us about cleanliness and proper disposal of urine. According to the Prophet Muhammad, boys' urine should be sprinkled over while girls' urine should be washed away. This is an important lesson for us to remember as it is related to hygiene and cleanliness which are essential for our health and wellbeing. It also shows us how we can take care of our environment by disposing off waste properly. Furthermore, this hadith also teaches us about gender equality as both boys and girls are given equal importance when it comes to hygiene practices.
