Explaining what falls under fitnah (trial, discord or temptation) regarding the proliferation of names, sects, and parties

Question:
In the name of Allah, the Most Gracious, the Most Merciful. Honorable Shaykh. The questioner asks: Does what we hear in these days regarding the proliferation of names, sects, and parties fall under fitnah (trial, discord or temptation)? And what do you advise us? Is there a basis for these names and these sects?

Answer:
Yes. The Prophet (peace and blessings be upon him) encouraged us to unite, to agree, and to hold fast to the Book of Allah, the Sunnah of His Messenger, and to follow the methodology of the righteous Salaf. He warned us against disagreement, whatever that disagreement may be. Whatever that disagreement may be.
And whatever name it is given, it is disagreement, fitnah (trial, discord or temptation), and evil. Therefore, it is obligatory for Muslims in general, and for students of knowledge in particular, to hold fast to what the people of the Sunnah and the community are upon. And these lands, praise be to Allah, their state was established from the time of Shaykh Muhammad ibn 'Abd al-Wahhab to our present time, differing from the Islamic states in these lands, they were established on one path, which is the path of the Book, the Sunnah, sound creed, and following the methodology of the Salaf. So if anyone wants to change us from this direction and bring us imported calls or newly invented methodologies, we disavow to Allah from that, and we hold fast to what we are upon. We are not in doubt, we are not in doubt about what we are upon, such that we look left and right for imported schools of thought, parties, groups, and sects. We are not in doubt about the soundness of our methodology and the correctness of what we are upon. If these people want good, let them join us and enter with us into what we are in, and help us, and we will help them in that. But if they want to divert us from what we are upon to what they want, then no hearing and no obedience. Yes.
