As-Sajdah 17

فَلَا تَعْلَمُ نَفْسٌ مَّآ أُخْفِىَ لَهُم مِّن قُرَّةِ أَعْيُنٍ جَزَآءًۢ بِمَا كَانُوا۟ يَعْمَلُونَ

falā taʿlamu nafsun mā ukh'fiya lahum min qurrati aʿyunin jazāan bimā kānū yaʿmalūna

And no soul knows what has been hidden for them of comfort for eyes [i.e., satisfaction] as reward for what they used to do.
