فَاَثَابَهُمُ اللّٰهُ بِمَا قَالُوْا جَنّٰتٍ تَجْرِيْ مِنْ تَحْتِهَا الْاَنْهٰرُ خٰلِدِيْنَ فِيْهَاۗ وَذٰلِكَ جَزَاۤءُ الْمُحْسِنِيْنَ ( المائدة: ٨٥ )
Fa asaabahumul laahu bimaa qaaloo Jannnaatin tajree min tahtihal anhaaru khaalideena feehaa; wa zaalika jazaaa'ul muhsineen (al-Māʾidah 5:85)
So Allah rewarded them for what they said with gardens [in Paradise] beneath which rivers flow, wherein they abide eternally. And that is the reward of doers of good. (Al-Ma'idah  : 85)

So, because of what they said, Allah has awarded them gardens beneath which rivers flow, wherein they will live forever. That is the reward of those who are good in their deeds.
