There’s Only One Person Who Should Be Followed Completely

Imām Ibn Taimiyyah, may Allāh have mercy on him, said:

Everyone who takes other than the Messenger of Allāh ﷺ–a shaikh or scholar–as someone to be followed in everything he says or does, attaching himself with love and support for those who agree with [that shaikh] and detaching himself with enmity against those who oppose him, is a deviant innovator, one who has left the Book and the Sunnah.
