messenger's duty

وَأَطِيعُوا۟ ٱللَّهَ وَأَطِيعُوا۟ ٱلرَّسُولَ وَٱحْذَرُوا۟ ۚ فَإِن تَوَلَّيْتُمْ فَٱعْلَمُوٓا۟ أَنَّمَا عَلَىٰ رَسُولِنَا ٱلْبَلَـٰغُ ٱلْمُبِينُ

And obey Allāh and obey the Messenger and beware. And if you turn away - then know that upon Our Messenger is only [the responsibility for] clear notification.

وَإِن تُكَذِّبُوا۟ فَقَدْ كَذَّبَ أُمَمٌ مِّن قَبْلِكُمْ ۖ وَمَا عَلَى ٱلرَّسُولِ إِلَّا ٱلْبَلَـٰغُ ٱلْمُبِينُ

And if you [people] deny [the message] - already nations before you have denied. And there is not upon the Messenger except [the duty of] clear notification.
