Shaykh Ubayd al-Jābirī (hafidahullah):

As for a person who is upon misguidance and he presents himself as if he is upon the Sunnah (to cover up his misguidance), then indeed Allāh will expose him, unmask him and remove his covering.

For how many misguided individuals have there been, presenting a good beautiful attractive face, using the Book and Sunnah as evidence for that, then afterwards Allāh exposes him because he is a habitual liar and is not upon the Sunnah outwardly or inwardly.
