Surah Al-Anfal, ayah 40

وَإِن تَوَلَّوۡاْ فَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ مَوۡلَىٰكُمۡۚ نِعۡمَ ٱلۡمَوۡلَىٰ وَنِعۡمَ ٱلنَّصِيرُ ٤٠

Wa in tawallaw fa'lamū annallāha mawlākum ni'mal-mawlā wani'man-nasīr

But if they turn away - then know that Allāh is your protector. Excellent is the protector, and excellent is the helper.
