say obey god and obey the apostle. if you turn away then for him is his duty to fulfil and for you the burden that you carry yet if you obey him you will be rightly guided. the duty of the messenger is to convey 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
