﴿ ثُمَّ إِنَّكُمْ يَوْمَ ٱلْقِيَٰمَةِ عِندَ رَبِّكُمْ تَخْتَصِمُونَ ﴾

“and then, behold, on the Day of Resurrection you all shall place your dispute before your Sustainer.”

Then lo! on the Day of Resurrection, before your Lord ye will dispute) i.e. the Prophet (pbuh) and the chieftains of the disbelievers will present their proof against each other.
