He who obeys the Messenger has obeyed Allah; but those who turn away - We have not sent you over them as a guardian.
The Saheeh International Quran Translation
مَّن يُطِعِ ٱلرَّسُولَ فَقَدْ أَطَاعَ ٱللَّهَ وَمَن تَوَلَّىٰ فَمَآ أَرْسَلْنَٰكَ عَلَيْهِمْ حَفِيظًاHe who obeys the Messenger has obeyed Allah; but those who turn away - We have not sent you over them as a guardian.
