Tafsir of Surah Al-Bayyina 98:8
﴿جَزَاؤُهُمْ عِندَ رَبِّهِمْ جَنَّاتُ عَدْنٍ تَجْرِي مِن تَحْتِهَا الْأَنْهَارُ خَالِدِينَ فِيهَا أَبَدًا رَّضِيَ اللَّهُ عَنْهُمْ وَرَضُوا عَنْهُ ذَٰلِكَ لِمَنْ خَشِيَ رَبَّهُ﴾
Translation of the meaning
Their reward with their Lord will be gardens of perpetual residence beneath which rivers flow, wherein they will abide forever, Allāh being pleased with them and they with Him. That is for whoever has feared his Lord.
