Is raising a grave (tashyeed) preferable to leveling it (tasteeh)?

Primary text

Raising the grave (tasneem) is the preferred manner for constructing a grave. This view is held by Malik, Abu Hanifa, and Ath-Thawri. The evidence supporting this preference is derived from the narration of Sufyan At-Tammar, who reported seeing the grave of the Prophet, peace be upon him, raised (musannam). Al-Hasan reported similarly. Furthermore, leveling the grave resembles the structures of the people of this world and is closer to the distinctive marks of innovators, thus making leveling disliked (makrooh). The evidence for raising the grave is deemed sounder and more established than the evidence for leveling.
