Musannaf Ibn Abi Shaybah 12154 — Levelling the grave, and reports

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.
