(Zumar) 39 : 31
ثُمَّ إِنَّكُمْ يَوْمَ الْقِيَامَةِ عِنْدَ رَبِّكُمْ تَخْتَصِمُونَ
Then indeed you will argue near your Lord on the Day of Judgement.
Messengers and believers who were testifying to Adhikr in this world will witness against the disbelieving Fujjar on the Day of Judgment. Moreover, the hypocritical disbelievers and their disbelieving followers will blame, curse, and argue with each other on the Day of Judgment, as explained in verses 2: 165-167. See explanation 4: 41-42; 11: 17; 25: 17-18, 29-30.
