Quran Ash-Shuraa 42:10
وَمَا ٱخۡتَلَفۡتُمۡ فِيهِ مِن شَيۡءٖ فَحُكۡمُهُۥٓ إِلَى ٱللَّهِۚ ذَٰلِكُمُ ٱللَّهُ رَبِّي عَلَيۡهِ تَوَكَّلۡتُ وَإِلَيۡهِ أُنِيبُ ١٠
Translation
And in anything over which you disagree - its ruling is [to be referred] to Allāh. [Say], "That is Allāh, my Lord; upon Him I have relied, and to Him I turn back."
