Showing Loyalty Or Enmity For Other Than The Prophet (saw), By Ibn Taymiyyah
Shaykh-ul-Islaam Ibn Taymiyyah said:
“It is not for anyone to place for the ummah a person calling to his path showing loyalty or enmity because of that path other than the Messenger of Allaah (sal-Allaahu ‘alayhe wa sallam).
And it is not permissible to place for them speech, show loyalty or enmity because of it other than the speech of Allaah and His messenger (sal-Allaahu ‘alayhe wa sallam) and that which The Ummah has united upon.
Rather, this is what the people of innovation do who place for themselves a person or some speech and they divide with it the ummah, showing loyalty or enmity upon that person or that kalaam or that attribute.”
