The heaven is beyond one's hearing, imagination

The residents of heaven will remain young for ever, their clothes will never be old

There are four kinds of rivers in heaven

Meaning: The messenger of Allah صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ said: In Paradise there is a sea of water, a sea of honey, a sea of milk, and a sea of wine. Then the rivers will split after that.
