It is narrated from Ubaidullah bin Umar that Umar bin Abdul Aziz, may Allah have mercy on him, delivered a sermon and said: O people! Indeed, after your Prophet, Allah has not sent any prophet, nor has He revealed any book after the book which He sent down upon him. Therefore, whatever has been declared lawful by your Prophet (peace be upon him) through his tongue is lawful until the Day of Resurrection, and whatever has been declared unlawful by your Prophet through his tongue is unlawful until the Day of Resurrection. Listen! I am not a judge, but a critic, and I am not an innovator, but a follower. And I am not better than you except that I have more burden (responsibility) upon me than you. And listen! There is no one among Allah’s creation whose obedience should be in the disobedience of Allah. Listen! Have I conveyed (the message) to you?
