وَقَالَتِ ٱلْيَهُودُ عُزَيْرٌ ٱبْنُ ٱللَّهِ وَقَالَتِ ٱلنَّصَٰرَى ٱلْمَسِيحُ ٱبْنُ ٱللَّهِ ۖ ذَٰلِكَ قَوْلُهُم بِأَفْوَٰهِهِمْ ۖ يُضَٰهِـُٔونَ قَوْلَ ٱلَّذِينَ كَفَرُوا۟ مِن قَبْلُ ۚ قَٰتَلَهُمُ ٱللَّهُ ۚ أَنَّىٰ يُؤْفَكُونَ
And the Jews say: Ezra is the son of Allah, and the Christians say: The Messiah is the son of Allah. That is their saying with their mouths. They imitate the saying of those who disbelieved of old. Allah (Himself) fighteth against them. How perverse are they!
