Pray in designated areas such as mosques instead of gravesites or shrines; Respect the dead; Avoid worshipping idols; Avoid shirk/polytheism/grave-worshipping.

In this hadith, Prophet Muhammad (PBUH) is warning us against taking graves as places of worship and prostration. He prayed to Allah not to make his grave an idol that is worshipped. This hadith teaches us that we should never take any grave or shrine as a place for worship or prostration because it is considered a form of idolatry and it angers Allah greatly. We should only pray in mosques and other designated places for prayer and never at any gravesite or shrine.
