The ruling on lighting a fire after burying the deceased out of fear of wild beasts

Question:
Some people in the southern region, when they bury the deceased, light a fire for a week, out of fear that a wild beast will come and take the heart of the corpse. How do you advise these people?

Answer:
This has no basis. This person asks, saying: Some people in the south light a fire at the grave after burial for a week. They say: We fear that a wild beast will come, dig up the grave, and take something from the deceased. This is something we have not heard of except in this question; we have not heard of it regarding the south except from this questioner. In any case, if this has occurred, it is not permissible.
It is obligatory for them to dig deep. They should dig the graves deep and place bricks or stones on them until they are hidden from wild beasts and others. The Prophet (peace and blessings be upon him) said to the digger: Dig and go deep. The digger digs and goes deep in the grave so that it is far from the reach of wild beasts, dogs, and the like. If it is in solid ground, he covers the grave with stones and secures it with stones. There is no need for a fire; there is no need for that.
