Is the world a dungeon for believers?
According to a narration, the world is a dungeon for believers and a paradise for the infidel. However, according to the Quran, Allah has created all the beauties of the world for the believers and nobody can forbid them:
“Say, “Who has forbidden the adornment of Allah which He has produced for His servants and the good things of provision?” Say, “They are for those who believe during the worldly life [but] exclusively for them on the Day of Resurrection.” (al-Araf  32).
Therefore, the world isn’t a dungeon for the believers. It’s a place to notice the beauties which Allah has created and to be thankful for them.
