The true shaheeds will continue to be sustained by their lord in their graves in the way Allah knows best. They will be raised on the day of judgement with bloodied bodys and faces shining bright.
There is nothing more that they would wish for than to be sent back to the earth so that they can die in the sameway again and again because of the special feeling a shaheed gets at the moment of death. They will enjoy the loftiest of ranks which Allah has reserved for those who died for his pleasure.
They will be most happy with their lord just like their lord will be most happy with them. They will be the envy of ALL on the day of judgement and everyone will wish to have died in the same way as them for the pleasure of Allah.
