Qur'an 39:36

أَلَيْسَ ٱللَّهُ بِكَافٍ عَبْدَهُۥ ۖ وَيُخَوِّفُونَكَ بِٱلَّذِينَ مِن دُونِهِۦ ۚ وَمَن يُضْلِلِ ٱللَّهُ فَمَا لَهُۥ مِنْ هَادٍ

“Is not Allāh sufficient for His Servant [i.e., Prophet Muḥammad (ﷺ)]? And [yet], they threaten you with those [they worship] other than Him. And whoever Allāh leaves astray - for him there is no guide.”
