Surah Taha, ayah 76

جَنَّٰتُ عَدۡنٖ تَجۡرِي مِن تَحۡتِهَا ٱلۡأَنۡهَٰرُ خَٰلِدِينَ فِيهَاۚ وَذَٰلِكَ جَزَآءُ مَن تَزَكَّىٰ ٧٦

Jannātu 'adnin tajrī min tahtihal-anhāru khālidīna fīhā wadhālika jazā'u man tazakkā

Gardens of perpetual residence beneath which rivers flow, wherein they abide eternally. And that is the reward of one who purifies himself.⁸⁴⁴
