Surah An-Nahl, ayah 51

۞ وَقَالَ ٱللَّهُ لَا تَتَّخِذُوٓاْ إِلَٰهَيۡنِ ٱثۡنَيۡنِۖ إِنَّمَا هُوَ إِلَٰهٞ وَٰحِدٞ فَإِيَّٰيَ فَٱرۡهَبُونِ ٥١

Waqālallāhu lā tattakhidhū ilāhaynithnayni innamā huwa ilāhun wāhidun fa iyyāya farhabūn

And Allāh has said, "Do not take for yourselves two⁷⁰² deities. He [i.e., Allāh] is but one God, so fear only Me."
