Is it true that the people of the Sunnah are three sects: the Salafis, the Asha'irah, and the Maturidiyyah?

The Shaykh : Because some scholars hold that the people of the Sunnah are three, three groups: the Asha'irah, the Maturidiyyah, and the Salafis. This is well-known among the later generations, but this is an error. The people of the Sunnah are those who adhere to the Sunnah. When that is the case, we say: either they are the Salafis or they are the Asha'irah, necessarily, because the two schools differ. And when the two schools differ, one of them is the truth. So who is more deserving of being described as the people of the Sunnah? The Salafis, without a doubt. For this reason, the only statement that is established is that we say: the people of the Sunnah are the Salaf and their followers. As for the Asha'irah, they are people of the Sunnah in what they did not contradict the people of the Sunnah in, but as for what they contradicted the people of the Sunnah in, they are not from the people of the Sunnah. And we say: it is possible for the description to be divided, so it is said: so-and-so is from the people of the Sunnah in such-and-such, and from the people of innovation in such-and-such. Just as we say: so-and-so is a believer in such-and-such, an open sinner in such-and-such. A believer in establishing the prayer, an open sinner in shaving the beard, for example. Yes, that is right.
The important thing is that the people of the Sunnah are the Salaf and their followers. As for the Asha'irah and the Maturidiyyah, they are people of the Sunnah in what they agreed with the Sunnah in. Yes.
