obey god and obey the messenger. if you turn away then he is responsible for what he is charged with and you are responsible for what you are charged with. if you obey him you will be rightly guided. the messenger is responsible only for delivering the message clearly.
قل أطيعوا الله وأطيعوا الرسول فإن تولوا فإنما عليه ما حمل وعليكم ما حملتم وإن تطيعوه تهتدوا وما على الرسول إلا البلاغ المبين
