Surah Taha, Verse 76

جَنَّٰتُ عَدۡنٖ تَجۡرِي مِن تَحۡتِهَا ٱلۡأَنۡهَٰرُ خَٰلِدِينَ فِيهَاۚ وَذَٰلِكَ جَزَآءُ مَن تَزَكَّىٰ٧٦

jannātu ʿadnin tajrī min taḥtihā l-anhāru khālidīna fīhā wadhālika jazāu man tazakkā

Gardens of perpetual residence beneath which rivers flow, wherein they abide eternally. And that is the reward of one who purifies himself.
