Salamun Alaikum.
I'm not sure about the exact words this person used but I once had a discussion with a non-Muslim who seemed to feel that it didn't make sense that the soul would (or could?) fall asleep in the grave as it is the body that sleeps and our body is only a shell to house the soul. They seemed to believe that the soul cannot sleep. I'm not too sure what the Qur'an says about this.
Does the Qur'an mention that we'll be raised in our bodies, or will only our souls be raised? If the latter, then that would mean that the soul will be asleep in the grave?
I know this isn't an important question but it's still interesting.
Thanks for any answers.
