Follow instructions from Prophet Muhammad , Respect those who have passed away .

The hadith narrated by Ali ibn Abi Talib tells us that the Prophet Muhammad sent him to the city of Madinah with an important task. He was instructed to level all of the graves in the city. This is a reminder for us that we should not build structures or monuments on top of graves as it is disrespectful and goes against Islamic teachings. We should also remember that death is a natural part of life and we should not be too attached to our loved ones who have passed away. Instead, we should focus on living our lives according to Islamic teachings so that when it's our time, we can meet them again in Jannah.
