Thumamah bin Shufa narrated: We were with Fadalah bin 'Ubaid in the land of the Romans, and a companion of ours died. Fadalah ordered that his grave be made level, then he said: 'I heard the Messenger of Allah commanding that it be made level. '
Ali said: Shall I not send you on the same mission as the Messenger of Allah sent me? Do not leave any raised grave without leveling it, or any image in a house without erasing it.
