"وأطيعوا الله وأطيعوا الرسول فإن توليتم فإنما على رسولنا البلاغ المبين".
Follow Allah and follow the Messenger. If you turn away from what the Messenger brought to you, then the sin of such turning away is to your detriment. The Messenger’s duty is only to convey what I have instructed him to convey, and He has conveyed what he was instructed to convey.
