السّجدة — As-Sajdah Ayat 17

فَلَا تَعْلَمُ نَفْسٌ مَّآ اُخْفِيَ لَهُمْ مِّنْ قُرَّةِ اَعْيُنٍۚ جَزَاۤءًۢ بِمَا كَانُوْا يَعْمَلُوْنَ

Falā ta‘lamu nafsum mā ukhfiya lahum min qurrati a‘yun(in), jazā'am bimā kānū ya‘malūn(a).

"And no soul knows what has been hidden for them of comfort for eyes as reward for what they used to do."
