The belief of Ahlus Sunnah is that the Holy Prophet Sallallahu Alaihe Wa Sallam is alive in his grave but his life in grave is not like the life of this world.
There are numerous Ahadith that support this belief of the Ahlus Sunnah Wal Jama'ah. This belief of the life of the Holy Prophet Sallallahu Alaihe Wa Sallam is applicable to the life of other Prophets of Allah as well.
