Musannaf Ibn Abi Shaybah

Hazrat Thumamah bin Shufay says that during the era of Hazrat Muawiyah, we set out from this city for a military expedition (battle), and Hazrat Fadala bin Ubaid was with us. His cousin Hazrat Nafi’ passed away. Hazrat Fadala stood with us at his grave. When we had buried him, he said: “Make his grave level and even, for indeed the Messenger of Allah (peace and blessings be upon him) commanded that graves be leveled.”
