Quran 29:58

وَٱلَّذِينَ ءَامَنُواْ وَعَمِلُواْ ٱلصَّـٰلِحَـٰتِ لَنُبَوِّئَنَّهُم مِّنَ ٱلۡجَنَّةِ غُرَفً۬ا تَجۡرِى مِن تَحۡتِہَا ٱلۡأَنۡهَـٰرُ خَـٰلِدِينَ فِيہَا‌ۚ نِعۡمَ أَجۡرُ ٱلۡعَـٰمِلِينَ ٥٨

Those who believe and lead a righteous life, we will surely settle them in Paradise, with mansions and flowing streams. Eternally they abide therein. What a beautiful reward for the workers.
