Show respect when entering someone's dwelling place; remember their suffering; weep for their fate; show compassion towards others; remember death is inevitable for all humans.

In this hadith, narrated by Abdullah bin Umar, Prophet Muhammad is warning us about entering the dwellings of those who lived in Al-Hijr. He said that if we do enter these places, it should be done with respect and humility. We should enter while weeping for their fate and what happened to them so that we don't suffer a similar fate. This hadith teaches us to show respect for those who have passed away and to remember their suffering so that it does not happen again. It also teaches us humility and reminds us that no matter how powerful or successful we become in life, our end will come one day just like everyone else's.
