﴿ ٱللَّهُ يَحْكُمُ بَيْنَكُمْ يَوْمَ ٱلْقِيَٰمَةِ فِيمَا كُنتُمْ فِيهِ تَخْتَلِفُونَ ﴾

“[For, indeed,] God will judge between you [all] on Resurrection Day with regard to all on which you were wont to differ.”

(Allah will judge between you on the Day of Resurrection concerning that wherein ye used to differ) regarding sacrifices and Allah's divine Oneness.
