Al-Qurtubi: The disbelief of the disbeliever does not prevent him from enjoying justice

Al-Qurtubi said concerning the verse, “O you who have believed, be persistently standing firm for Allah, witnesses in justice, and do not let the hatred of a people prevent you from being just,” (5:8) that this means “the disbelief of the disbeliever does not prevent him from enjoying justice.”

[Tafsir Al-Qurtubi, Verse 5:8]

يَا أَيُّهَا الَّذِينَ آمَنُوا كُونُوا قَوَّامِينَ لِلَّهِ شُهَدَاءَ بِالْقِسْطِ وَلَا يَجْرِمَنَّكُمْ شَنَآنُ قَوْمٍ عَلَىٰ أَلَّا تَعْدِلُوا

ودلّت الآية أيضاً على أن كفر الكافر لا يمنع من العدل عليه
