Is the original principle that we name ourselves as our Lord, Mighty and Majestic, named us Muslims, or do we name ourselves after the righteous predecessors?

The Shaykh : And finally, I say a word: Some people think that when they hear this explanation, they might say: "This is reasonable and beautiful talk, but is it not better that we remain as our Lord, Mighty and Majestic, named us, Muslims?" I say: Yes, without doubt, this is the best, but that is only when it is possible to remain with this designation, when it is possible to maintain this designation. And without doubt, we cannot imagine this being realized except when all Muslims become truly Muslims, when all these designations we spoke about, along with their dangers and their consequences that contradict the Shari'ah, are eliminated.
As for the majority of the people of the Sunnah, they affiliate with one of these four schools of jurisprudence. If we return their disapproval of our affiliation with the righteous predecessors back to them, we return this disapproval to them as our disapproval of their affiliation with the Hanafi or Shafi'i school. If they remain satisfied with their various, multiple designations that affiliate them to a person who is not infallible, and which have those effects we illustrated with some examples, how is it permissible for us to submit to their request that we not affiliate with the righteous predecessors, in which there is infallibility as we mentioned, while they affiliate with individual scholars, in which there is no infallibility as we have explained?
So, on the day when these deniers of this true designation adopt the principle of returning to the divine name, or we are content that we are Muslims and that is enough, and they apply that to themselves, on that day it is possible—I say it is possible—that we agree not to affiliate with any designation other than that we are Muslims.
And I do not say this with certainty; I say it is possible, because I imagine that no matter how much Muslims strive—and their number has reached eight hundred million, nine hundred million Muslims—no matter how much the best of them strive to remain content with the Book and the Sunnah, a large portion of them will remain deviating from the Book and the Sunnah. And this deviation will lead them to remain in their current state of many deviations, among which is affiliating with one who is not infallible.
