The respected Sheikh (May Allah preserve him upon good) makes sense. In his another video he said something along these lines that instead of arguing, slandering and mocking people from others' sects, we should ignore the minor ikhtilfat and should protect our Islam and Muslims from the kuffar (May Allah destroy them), thats why I've more respect for this Sheikh.
Whilst I'm not denying there're deviants in different groups but we should ignore the minor differences and should refrain from labeling others as deviants, just because we know no different, or were taught one way and not another.
I follow the hanafi madhab but people shouldn't expect me to be 'not doubtful' regarding some matters. There're ikhtilfat among the Ulama even in the same madhhab. The possibility of making mistakes is there. I believe every individual other than the Nabi sallalaho alaihi wasallam is sometimes incorrect & sometimes correct.
Just because a Sufi scholar is wrong in an area or in multiple areas, this does not mean that they are wrong in all other areas and that nothing should be taken from them. This holds true for the Salafi and even Zahiri scholars and their erroneous ways. We are after all humans and are prone to make mistakes now and again. The only humans that never made a mistake are the Prophets alaihs salam.
In essence, what I have come across was that each and every group claims to be following the Qur'an and Sunnah. Whereas in reality the truth sometimes might be at a stark contrast to this claim. There are flaws in every sect (even in the sect of those of us that claim to be sunni, deobundi, Hanafi etc. believe it or not!) The difference is that some sects are more closer to the truth some are less.
So, The Muslims who are sincere, no matter what sect they're in, will Insha Allah get Jannah!
