Narrated Abu 'Ali al-Hamdani: We were with Fudalah b. 'Ubaid at Rudis in the land of Rome. One of our Companions dies, Fudalah commanded us to dig his grave; it was (dug and) levelled. He then said: I heard the Messenger of Allah (ﷺ) commanding to level them. Abu Dawud said: Rudis is an island, in the sea
