وَٱلَّذِينَ يُحَآجُّونَ فِى ٱللَّهِ مِنۢ بَعْدِ مَا ٱسْتُجِيبَ لَهُۥ حُجَّتُهُمْ دَاحِضَةٌ عِندَ رَبِّهِمْ وَعَلَيْهِمْ غَضَبٌۭ وَلَهُمْ عَذَابٌۭ شَدِيدٌ
And those who argue concerning Allah after He hath been acknowledged, their argument hath no weight with their Lord, and wrath is upon them and theirs will be an awful doom.
