The reason for leaving the mosque over the grave of the Prophet (peace and blessings be upon him)

Question:
Honorable Shaykh, may Allah grant you success, there are many questions asking why the mosque remains over the grave of the Prophet (peace and blessings be upon him), especially since the grave predates the mosque, and so that the innovators cannot use this as an argument. What is the reason for leaving it as it is?

Answer:
Fear of fitnah (trial, discord or temptation), fear of fitnah from the people, because the people have been accustomed to this for a long time. If it were changed, fitnah would occur. The Messenger of Allah (peace and blessings be upon him) refrained from rebuilding the Ka'bah on the foundations of Ibrahim out of fear of fitnah. He said (peace and blessings be upon him): on the foundations of Ibrahim. The Messenger (peace and blessings be upon him) left the rebuilding of the Ka'bah on the foundations of Ibrahim out of fear of fitnah. So averting harm takes precedence over seeking benefit. And the grave, praise be to Allah, is now protected within the walls, and there are guards over it, and no one is able to perform innovations at it. This is from the favor of Allah and His facilitation, and an answer to the supplication of the Messenger (peace and blessings be upon him) when he said: "O Allah, do not make my grave an idol to be worshipped." Allah made it easy for those who protect it throughout the ages, and praise be to Allah. Yes.
