An-Nisa 4:80

مَّن يُطِعِ ٱلرَّسُولَ فَقَدْ أَطَاعَ ٱللَّهَ ۖ وَمَن تَوَلَّىٰ فَمَآ أَرْسَلْنَـٰكَ عَلَيْهِمْ حَفِيظًا

Man yuṭiʿi l-rasūla faqad aṭāʿa l-laha waman tawallā famā arsalnāka ʿalayhim ḥafīẓan

He who obeys the Messenger has obeyed Allāh; but those who turn away - We have not sent you over them as a guardian.
