Is it permissible to raise or flatten the graves and make ploughing fields on it? If a Muslim does such an act, what is the ruling for such a person?
This is Haram. Yes, in the situation of when the land was owned by a person and the deceased were buried in the owner’s land, without his permission, then the owner has the right to exhume the graves and use the land as he wishes.
And Allah ﷻ knows the best
