The Prophet (sal Allahu alaihi wa sallam) said, “Allah has cursed the male and female grave digger”
[Related by Imam Al-Baihaqee and it is Authentic]
Another person who is cursed by Allah is the grave digger. This is the person who visits the graves at night, away from the sight of people and digs them up in search for items of benefit and use to him. He may remove some jewellery and other materials buried with the deceased and even the shroud that the deceased is wrapped in. This cursed individual continues his rotten deeds by selling these items to make money from them or keeping them for personal use.
And Allah knows best!
