Some people believe that Resurrection is the rising of the spirit after death and some believe the body as well, because the Bible says:
Do not marvel at this, for an hour is coming when all who are in the tombs will hear his voice and come out, those who have done good to the resurrection of life, and those who have done evil to the resurrection of judgment
Having a hope in God, which these men themselves accept, that there will be a resurrection of both the just and the unjust
And you will be blessed, because they cannot repay you. For you will be repaid at the resurrection of the just.”
Yet a little while and the world will see me no more, but you will see me. Because I live, you also will live.
When the Sabbath was past, Mary Magdalene and Mary the mother of James and Salome bought spices, so that they might go and anoint him. And very early on the first day of the week, when the sun had risen, they went to the tomb. And they were saying to one another, “Who will roll away the stone for us from the entrance of the tomb?” And looking up, they saw that the stone had been rolled back—it was very large. And entering the tomb, they saw a young man sitting on the right side, dressed in a white robe, and they were alarmed. …
1 Thessalonians 4:16
For the Lord himself will descend from heaven with a cry of command, with the voice of an archangel, and with the sound of the trumpet of God. And the dead in Christ will rise first.
And many of those who sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt
1 Thessalonians 4:14
For since we believe that Jesus died and rose again, even so, through Jesus, God will bring with him those who have fallen asleep.
For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day
While the Quran describe it as: (just a few verses)
God is He Who raised the heavens without any pillars that you can see, then He established Himself upon the Throne (of authority; having shaped the universe and made it dependent upon certain laws, He exercises His absolute authority over the whole of the universe), and subjected the sun and the moon (to His command); each runs (its course) for an appointed term. He regulates all affair, expounding the signs, that you may believe with certainty in the meeting with your Lord. (13:2)
Among His signs is that you see the earth dry and barren; and when We send down rain on it, it stirs to life and swells. Surely God Who gives the dead earth life will raise the dead also to life. Indeed, He has power over all things. (41:39)
O mankind! If you are in doubt concerning the Resurrection, (consider that) We created you of dust, then of semen, then of a fertilized ovum suspended on the wall of the womb, then of a lump of flesh shaped and unshaped, so that We demonstrate to you Our power. And We keep in the wombs what We please to an appointed term, and afterwards We bring you forth as infants, then We cause you to grow up, that you reach your prime. Among you some die (young) and some are sent back to the feeblest phase of age so that they know nothing after they had knowledge. You sometimes see the earth dry and barren. But when We pour down rain on it, it trembles, and swells, and grows of every pleasant pair. That is so because God is the Truth, and He it is Who gives life to the dead, and He is powerful over all things. (22:5-6)
Does man think that he will be left to himself uncontrolled (without purpose)? Was he not a drop of fluid which gushed forth? Then he became a clinging clot; then He shaped and fashioned, and made of him a pair, the male and female. Is He then not able to raise the dead to life? (75:36-40)
Look at the prints of God’s Mercy: how He gives life to the earth after its death. Lo! He verily is the Reviver of the dead (in the same way), and He is able to do all things. (30:50)
God has brought you forth from the earth like a plant. And to the earth He will restore you. Then He will bring you back fresh. (71:17-8)
Qaf 50: 41-44
41. And listen on the Day when the caller will call from a near place,
42. The Day when they will hear As-Saihah (shout, etc.) in truth, that will be the Day of coming out (from the graves i.e. the Day of Resurrection).
43. Verily, We it is Who give life and cause death; and to Us is the final return,
44. On the Day when the earth shall be cleft, from off them, (they will come out) hastening forth. That will be a gathering, quite easy for Us
I’ve found this book (pdf) which is funny and gives more details on the subject:
So for those who think that we’ll be ghost, I believe it’s better to think twice
