Levelling the grave, and reports on it

Thumamah bin Shufayy says: We set out on a military expedition in the time of Sayyiduna Mu'awiyah (may Allah be pleased with him) towards this mountain pass, and our commander was Sayyiduna Fadalah bin Ubayd (may Allah be pleased with him). A cousin of mine called Nafi' passed away, and Sayyiduna Fadalah stood with us at his grave. When we had buried him, he said: "Make his grave light and level, for the Messenger of Allah (peace and blessings be upon him) used to order that graves be levelled."

Abdullah bin Shurahbil says that Sayyiduna Uthman (may Allah be pleased with him) went out and ordered that the graves be levelled. We levelled all the graves except the grave of Umm Amr, the daughter of Uthman. He asked: "Whose grave is this?" The people said: "It is the grave of Umm Amr." He ordered that it too be levelled, and so it was levelled as well.

Hanash al-Kinani says that Sayyiduna Ali (may Allah be pleased with him) went to the chief of the police and said to him: "Go, and do not leave any ornamentation without bringing it down, and do not leave any grave without levelling it." Then he called him back and asked: "Do you know for what task I have sent you? I have sent you for the task for which the Messenger of Allah (peace and blessings be upon him) sent me."

A freed slave of Sayyiduna Ibn Abbas (may Allah be pleased with them both) says that Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) said to me: "When you see people who have buried a dead person and made his grave in a way unlike the graves of the Muslims, then level it to be like the graves of the Muslims."

Abu Mijlaz says that levelling the graves is part of the Sunnah.

Something similar is reported from Abu Mijlaz.

Mansur bin Abd al-Rahman says that a man said to Imam al-Sha'bi: "A man buried his deceased and made his grave level with the ground (is that correct?)" He said: "I have seen the graves of the martyrs of Uhud, and they are raised up above the ground."
