وَأَطِيعُوا اللَّهَ وَأَطِيعُوا الرَّسُولَ وَاحْذَرُوا ۚ فَإِنْ تَوَلَّيْتُمْ فَاعْلَمُوا أَنَّمَا عَلَىٰ رَسُولِنَا الْبَلَاغُ الْمُبِينُ 92
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.
