Quran 4:122 An-Nisa, ayah 122 of 176

وَٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ سَنُدْخِلُهُمْ جَنَّـٰتٍ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَـٰرُ خَـٰلِدِينَ فِيهَآ أَبَدًا ۖ وَعْدَ ٱللَّهِ حَقًّا ۚ وَمَنْ أَصْدَقُ مِنَ ٱللَّهِ قِيلًا ۝١٢٢

4:122 But as for those who believe and do good works We shall bring them into Gardens underneath which rivers flow, wherein they will abide for ever. It is a promise from Allah in truth; and who can be more truthful than Allah in utterance?
