How to bury in land where water rises

The questioner:
Regarding burial, the grave is at a moderate depth, and there is nothing else near the water source, which is the sea. Water reaches the deceased from beneath the ground, so they were forced to build around the grave and raise the body so that it is not in a pit in the ground. They build over it with brick and place an iron cover over it, out of fear for the body from the water. That is all.

The Shaykh:
And what do they put to prevent it, out of caution?

The questioner:
They found nothing but the cement bricks on the road, and this.

The Shaykh:
And what do they put, out of caution, slabs or something to prevent the water, and then they place the body on it, out of caution?

The questioner:
Wood.

The Shaykh:
Wood, or plaster, or stone.

The questioner:
Except what he earns.

The Shaykh:
Stone, stone now, one.

The questioner:
But this brick, no.

The Shaykh:
If they study it, they build over the deceased or plaster over him, but they place stones or slabs, then they bury the deceased, then they place what is above him.

The questioner:
Inside the ground, it is necessary, meaning it does not work on the surface. It must be decided.

The Shaykh:
Something that prevents the money, but this is it.
