Qur'ān 9:129 · At-Tawbah (التوبة)

فَإِن تَوَلَّوْا۟ فَقُلْ حَسْبِىَ ٱللَّهُ لَآ إِلَـٰهَ إِلَّا هُوَ ۖ عَلَيْهِ تَوَكَّلْتُ ۖ وَهُوَ رَبُّ ٱلْعَرْشِ ٱلْعَظِيمِ

But if they turn away, [O Muhammad], say, "Sufficient for me is Allah; there is no deity except Him. On Him I have relied, and He is the Lord of the Great Throne."
