Hadith on Qubur: Making graves levelled flat with the earth

Thamamah ibn Shufayy reported: We were with Fadalah ibn ‘Ubayd in the land of the Romans by a place known as Rudis. One of our companions passed away, so Fadalah ordered his grave to be levelled flat. Then, Fadalah said, “I heard the Messenger of Allah, peace and blessings be upon him, ordering them to be leveled.”
