﴿ وَأَطِيعُوا۟ ٱللَّهَ وَأَطِيعُوا۟ ٱلرَّسُولَ ۚ فَإِن تَوَلَّيْتُمْ فَإِنَّمَا عَلَىٰ رَسُولِنَا ٱلْبَلَٰغُ ٱلْمُبِينُ ﴾

“Pay heed, then, unto God, and pay heed unto the Apostle; and if you turn away, [know that] Our Apostle's only duty is a clear delivery of this message:”

(Obey Allah) with regard to His obligations (and obey His messenger) with regard to his practices; it is also said this means: obey Allah regarding Allah's divine Oneness and obey His Messenger by accepting his message; (but if ye turn away) from their obedience, (then the duty of Our messenger) Muhammad (pbuh) (is only to convey (the message)) on behalf of Allah (plainly) i.e. in a language that you understand.
