Allah's Ultimate Authority

ثُمَّ لَـَٔاتِيَنَّهُم مِّنۢ بَيْنِ أَيْدِيهِمْ وَمِنْ خَلْفِهِمْ وَعَنْ أَيْمَـٰنِهِمْ وَعَن شَمَآئِلِهِمْ ۖ وَلَا تَجِدُ أَكْثَرَهُمْ شَـٰكِرِينَ

Then I will come to them from before them and from behind them and on their right and on their left, and You will not find most of them grateful [to You]."

ٱللَّهُ يَحْكُمُ بَيْنَكُمْ يَوْمَ ٱلْقِيَـٰمَةِ فِيمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ

Allāh will judge between you on the Day of Resurrection concerning that over which you used to differ."
