And the Hour is coming without any doubt and Allah will raise up all those in the graves. (Qur'an, 22:7)
They will emerge from their graves with downcast eyes, like swarming locusts, necks outstretched, eyes transfixed, rushing headlong to the Summoner. The unbelievers will say, 'This is a pitiless day!' (Qur'an, 54:7-8)
Does man reckon he will be left to go on unchecked? Was he not a drop of ejaculated sperm, then an alaq (embryo) which He created and shaped, making from it both sexes, male and female? Is He Who does this not able to bring the dead to life? (Qur'an, 75:36-40)
The Trumpet will be blown and at once they will be sliding from their graves towards their Lord. (Qur'an, 36:51)
