Hi Glo.

In addition to the great replies already given, the key words in my reply was compared to. So compared to paradise, this world is like a prison. And of course it would be, when you consider that Allah swt has prepared for the believers 'what no eye has ever seen' etc. In earth we have so much restraints, but in paradise we can have whatever we want.

That doesnt mean that we have to feel like we are in a prison lol. But no one can deny that this life has hardships whereas paradise does not.
