Surah Al-Imran, ayah 98

قُلۡ يَٰٓأَهۡلَ ٱلۡكِتَٰبِ لِمَ تَكۡفُرُونَ بِـَٔايَٰتِ ٱللَّهِ وَٱللَّهُ شَهِيدٌ عَلَىٰ مَا تَعۡمَلُونَ ٩٨

Qul yā'ahlal-kitābi lima takfurūna bi'āyātillāhi wallāhu shahīdun 'alā mā ta'malūn

Say, "O People of the Scripture, why do you disbelieve in the verses of Allāh while Allāh is Witness over what you do?"
