Stand up when a funeral procession passes and do not sit down until the body is placed in the grave.

This hadith teaches us that it is important to show respect for those who have passed away. When a funeral procession passes, we should stand up out of respect and not sit down until the body has been placed in the grave. This shows our reverence for those who have died and reminds us of our own mortality. We should also remember that death can come at any time, so we should strive to live our lives in accordance with Islamic teachings while we still can.
