لَّقَدْ كَفَرَ ٱلَّذِينَ قَالُوٓا۟ إِنَّ ٱللَّهَ هُوَ ٱلْمَسِيحُ ٱبْنُ مَرْيَمَ ۚ قُلْ فَمَن يَمْلِكُ مِنَ ٱللَّهِ شَيْـًٔا إِنْ أَرَادَ أَن يُهْلِكَ ٱلْمَسِيحَ ٱبْنَ مَرْيَمَ وَأُمَّهُۥ وَمَن فِى ٱلْأَرْضِ جَمِيعًۭا ۗ وَلِلَّهِ مُلْكُ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضِ وَمَا بَيْنَهُمَا ۚ يَخْلُقُ مَا يَشَآءُ ۚ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍۢ قَدِيرٌۭ
They indeed have disbelieved who say: Lo! Allah is the Messiah, son of Mary. Say: Who then can do aught against Allah, if He had willed to destroy the Messiah son of Mary, and his mother and everyone on earth? Allah's is the Sovereignty of the heavens and the earth and all that is between them. He createth what He will. And Allah is Able to do all things.
