Do not sit on graves .

The Prophet Muhammad (PBUH) taught us to respect the dead by not sitting on their graves. This is because it is disrespectful to the deceased and can be seen as a form of disrespecting them. It also shows that we should remember our mortality and be mindful of our actions in life, as we will all eventually pass away. Additionally, this hadith teaches us to be humble and not take things for granted, such as life itself. We should always strive to live a good life so that when we die, people will remember us fondly and with respect.
