Al-Ahqaf - 46:14

أُوْلَئِكَ أَصْحَابُ الْجَنَّةِ خَالِدِينَ فِيهَا جَزَاء بِمَا كَانُوا يَعْمَلُونَ
[46:14]
These are the dwellers of the garden, abiding therein: a reward for what they did.
Such shall be Companions of the Gardens, dwelling therein (for aye): a recompense for their (good) deeds.
Such are rightful owners of the Garden, immortal therein, as a reward for what they used to do.
