How is the grave to torment one who died in an explosion, with nothing remaining of his body?

Whoever deserves punishment in the grave will be afflicted with what Allah has decreed for them. Allah is capable of punishing them regardless of their state of death. The punishment of the grave is the punishment of Al-Barzakh. So, anyone who dies deserving punishment will receive their share of it, whether they are buried or not. If wild animals devour them, or they are burned or drowned, the punishment will reach their soul and body just as it reaches the buried. It is obligatory to believe in the reality of the torment and bliss of the grave and the questioning by the two angels, and to have faith in it without delving into its nature.
