Al-Ma'idah' - 5:92

وَأَطِيعُواْ اللّهَ وَأَطِيعُواْ الرَّسُولَ وَاحْذَرُواْ فَإِن تَوَلَّيْتُمْ فَاعْلَمُواْ أَنَّمَا عَلَى رَسُولِنَا الْبَلاَغُ الْمُبِينُ
[5:92]
And obey Allah and obey the messenger and be cautious; but if you turn back, then know that only a clear deliverance of the message is (incumbent) on Our messenger.
Obey Allah, and obey the Messenger, and beware (of evil): if ye do turn back, know ye that it is Our Messenger's duty to proclaim (the message) in the clearest manner.
Obey Allah and obey the messenger, and beware! But if ye turn away, then know that the duty of Our messenger is only plain conveyance (of the message).
