Never think of those martyred in the cause of Allah as dead.
In fact, they are alive with their Lord, well provided for—
rejoicing in Allah’s bounties and being delighted for those yet to join them.
There will be no fear for them, nor will they grieve.
They are joyful for receiving Allah’s grace and bounty,
and that Allah does not deny the reward of the believers.
-- The Holy Quran, Surah Ali 'Imran 3:169-171
