Allamah Ibn Baaz advices some princes on how to deal with graves and tombs that could be a means for grave-worship
Message to a Prince from the Gulf States
From `Abdul `Aziz ibn `Abdullah ibn Baz to the honorable prince, may Allah grant him success and let Al-Haqq (the Truth) be victorious with his support! Amen.
As-salamu `alaykum warahmatullah wabarakatuh (May Allah's Peace, Mercy, and Blessings be upon you!)
Some sincere advisors wrote to me about a grave that is being worshipped instead of Allah in your country. Attached is a copy of his letter along with two photos of the said grave. I hope Your Eminence can issue an order to undermine this grave and prevent people from excessively praising it and offering sacrifices to its dweller. This is because excessiveness related to graves is as an act of the first Jahiliyyah (pre-Islamic time of ignorance). Besides, drawing closer to the dwellers of graves by offering sacrifices or vows or seeking their help are acts of Jahiliyyah, which Muslim rulers should put an end to.
The mortal remains should be moved to the public cemetery; each corpse should be buried in a separate hole in the ground and its surface should be leveled like all other graves, in order to hide it from people, lest they should over-praise it again.
It is reported that `Umar ibn Al-Khattab (may Allah be pleased with him) did the same with the grave of Daniel, whom the Persians used to over-praise; he ordered them to dig thirteen graves during the daylight and put the corpse in one of them at night and then to level all the graves so that people could not discern his grave.
May Allah bless you wherever you are and make the religion victorious with your support! May Allah guide you to do that which He loves and that which pleases Him!
May Allah help you protect the purified Shari`ah (Islamic law) from contraventions! He is the Most Generous. As-salamu `alaykum warahmatullah wabarakatuh.
