﴿ جَنَّٰتُ عَدْنٍۢ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ خَٰلِدِينَ فِيهَا ۚ وَذَٰلِكَ جَزَآءُ مَن تَزَكَّىٰ ﴾

“gardens of perpetual bliss, through which running waters flow, therein to abide: for that shall be the recompense of all who attain to purity.”

the Gardens of Eden that is to say as a place of residence this jannātu ‘Adnin ‘Gardens of Eden’ is an explication thereof of al-darajātu’l-‘ulā ‘the highest degrees’ underneath which rivers flow abiding therein and that is the reward of him who keeps pure of sins.
