Suuratul -Saba Verse 26
قُلْ يَجْمَعُ بَيْنَنَا رَبُّنَا ثُمَّ يَفْتَحُ بَيْنَنَا بِٱلْحَقِّ وَهُوَ ٱلْفَتَّاحُ ٱلْعَلِيمُ ﴿٢٦
26. Say: “Our Lord will assemble us all together (on the Day of Resurrection), then He will judge between us with truth. And He is the All-Knowing Judge.”
Tafsir Ibn Kathir
﴿فَاللَّهُ يَحْكُمُ بَيْنَهُمْ يَوْمَ الْقِيَـمَةِ فِيمَا كَانُواْ فِيهِ يَخْتَلِفُونَ﴾
Allah will judge between them on the Day of Resurrection about that wherein they have been differing.
meaning, that Allah will gather them all on the Day of Return. On that Day, Allah will justly judge between them, for He is never unjust with anyone, even as little as the weight of an atom.
