The body in the next life is the same body as we have here...
The body in the next life is the same body as we have here, but its make-up is in such a way that the necessary wastes of a material body are not there. Right now we are unable to imagine this perfectly because these wastes and defecations are necessary parts of material beings. People have made a similitude for this. No matter how much you would try to make a fetus understand that outside of its mother's stomach is a huge world full of fruit, food, plants and animals he would not understand.
Man is the same way when he is in the stomach of the natural world in relation to the unnatural world. However much one wants to make man understand about the different attractions of the next world he will not understand. The Qurān said: “No one knows what has been kept hidden for them of comfort (in the hereafter) as a reward for what they used to do.” ^3 We will now discuss some verses related to the Resurrection.
The Rejectors Do Not Have Any Proof Those who reject the hereafter only say that it is impossible; they do not have any proof. In the same way that they reject the creation, they raise the question: how can Allah bring dead bones back to life? The biggest proof for the resurrection is the verse: “Verily, Allah is able to bring him back” ^4 One who was able to create the body out of a drop of sperm can create it out of a handful of dirt as well.
The Qurān even says that it is easier for him to do that. Bringing back to life is easier than creating from scratch. Another nice point has been made in chapter Qiyāmat : “We are able to make man's fingerprints.” ^5 Tantāwī, an Egyptian Qurānic scholar wrote that the point of the previous verse was unknown until the modern century. He claims that it is one of the miracles of the Qurān. Previously people did not pay attention to the fact that every person has a special fingerprint.
Four and a half billion people have different fingerprints. Because of this, people must give their fingerprints as a signature and there are places that catch criminals by finding their fingerprints. The Differences In People’s Faces No two people have the exact same face. Even twins have small differences. Similarly, no two voices are exactly the same. What atrocities would happen if they were the same? The order of the world would be destroyed.
There would not be a social life because nobody would be able to differentiate between two people. Here we can see that the wise Creator made a wise decision in this regard.
