قُلْ یٰۤاَهْلَ الْكِتٰبِ لِمَ تَكْفُرُوْنَ بِاٰیٰتِ اللّٰهِ وَاللّٰهُ شَهِیْدٌ عَلٰی مَا تَعْمَلُوْنَ ۟

Qul yaaa Ahlal Kitaabi lima takfuroona bi Aayaatillaahi wallaahu shaheedun 'alaa maa ta'maloon

“Say: "O People of the Book! Why reject ye the Signs of Allah, when Allah is Himself witness to all ye do?"”
