Al Maidah, 92 Ayah
5:92
وَأَطِيعُواْ ٱللَّهَ وَأَطِيعُواْ ٱلرَّسُولَ وَٱحۡذَرُواْۚ فَإِن تَوَلَّيۡتُمۡ فَٱعۡلَمُوٓاْ أَنَّمَا عَلَىٰ رَسُولِنَا ٱلۡبَلَٰغُ ٱلۡمُبِينُ ٩٢
Wa 'Aţī`ū Al-Laha Wa 'Aţī`ū Ar-Rasūla Wa Aĥdharū ۚ Fa'in Tawallaytum Fā`lamū 'Annamā `Alá Rasūlinā Al-Balāghu Al-Mubīnu
And obey Allah and obey the Messenger and beware. And if you turn away - then know that upon Our Messenger is only [the responsibility for] clear notification.
