In The Name of Allah, The Most Merciful, The Bestower of Mercy.

Imam Al-Awzaa’ee, may Allah have mercy upon him, said:

O Muslims! Fear Allah, accept the advice of the sincere advisers and the admonition of the admonishers. know that this knowledge is religion, so beware of what you do, from whom you take your religion, the one you follow, and the one with whom your religion is safe, because indeed all the proponents of religious innovation are falsifiers, liars, and sinners. They are not cautious – neither do they pay attention nor do they fear, and together with that they are not to be trusted that they would not distort what you hear.

They say what they do not know with regards to what they disapprove and when proclaiming their lies; but Allah (knows, hears, and sees) what they do. Therefore, be cautious of them, trust them not, reject them, and avoid them because this is what your earlier scholars did and commanded, and likewise the righteous ones who came thereafter.

Be careful of opposing Allah and being the means to destroying the religion He has ordained – breaking its commands and prohibitions, nullifying and weakening it by respecting the innovators in religious matters and those who initiate that which is not from the religion, because you know what has been transmitted (i.e. the prohibitions) about respecting or exalting them. What can be greater respect and exaltation than acquiring your religion from them- following and believing them, drawing close to them, and assisting them in enticing the ones they entice and wooing to their views and the religion (i.e. religious innovations) they follow? This is sufficient to be regarded as associates of theirs in what they do.
