يَوْمَ يَجْمَعُكُمْ لِيَوْمِ ٱلْجَمْعِ ۖ ذَٰلِكَ يَوْمُ ٱلتَّغَابُنِ ۗ وَمَن يُؤْمِنۢ بِٱللَّهِ وَيَعْمَلْ صَٰلِحًۭا يُكَفِّرْ عَنْهُ سَيِّـَٔاتِهِۦ وَيُدْخِلْهُ جَنَّٰتٍۢ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَٰرُ خَٰلِدِينَ فِيهَآ أَبَدًۭا ۚ ذَٰلِكَ ٱلْفَوْزُ ٱلْعَظِيمُ
The day when He shall gather you unto the Day of Assembling, that will be a day of mutual disillusion. And whoso believeth in Allah and doeth right, He will remit from him his evil deeds and will bring him unto Gardens underneath which rivers flow, therein to abide for ever. That is the supreme triumph.
Surah At-Taghaabun(64:9)
