Quran 32:17 from Surah As-Sajda on Divine Marvels.
فَلَا تَعۡلَمُ نَفۡسٞ مَّآ أُخۡفِيَ لَهُم مِّن قُرَّةِ أَعۡيُنٖ جَزَآءَۢ بِمَا كَانُواْ يَعۡمَلُونَ
English translation: And not knows a soul what is hidden for them of (the) comfort (for) the eyes (as) a reward for what they used (to) do
Transliteration: fala ta'lamu nafsun ma ukh'fiya lahum min qurrati a'yunin jazaan bima kanu ya'maluna
