Does deviating from the methodology in just one issue mean deviating from the methodology as a whole?

The questioner : I mentioned to some of the brothers a statement from those who call for factionalism. There is a hadith, and this is a newly invented matter among us. They used to say that deviating from the methodology in one issue means deviating from the methodology as a whole. Then they allow for deviations. So how do we refute them? That is, they say deviation in one issue...

The Shaykh : We return their goods to them, and the matter is ended.

The questioner : That is, we refute them with what...
onAl-Halabi : With what they said.

The questioner : With what they said. Good, is their statement correct? That is...

The Shaykh : No, it is not correct at all. But in any case, it contradicts the methodology. This is like faith and Islam. If a believer or a Muslim leaves something of the implications of faith and Islam, does that mean he has exited his faith and his Islam? The answer is no, but he has contradicted his faith and contradicted his Islam. Likewise, the one who departs from his methodology in one issue has contradicted his methodology. As for him opposing the methodology and exiting the methodology, that is not the case. But if they say this, we hold them to their statement and say to them: Where are you now, when you used to say that you have exited the methodology in one, in a second, in a third, and so on?

The questioner : May Allah reward you with the best reward.

The Shaykh : And you as well.
