Just re-read my post ^ and not happy with what I wrote.
Basically, Tawheed does not need to be 'split' up into anything, because it comes as a package. Obviously during the time of the Prophet (Peace be upon him), Tawheed didn't need to be split into anything, and today.. due to the different interpretations etc, people have taken sections out and explained things differently in order to fully understand what Tawheed entails, so you will get people saying it is 'split' up.
Tawheed is quite a big thing, and claiming it wrongly can really decrease the level of iman you have. Just like the Shaahadah- you testify it by tongue and believe in it too, right?
In all honesty, I ain't that knowledgeable, yet still on the learning ladder. Just stick with having a strong faith & the 7 fundamental beliefs intact and inshAllah; you won't go wrong.
Having a strong faith enables you to trust Allah Almighty, coz he knows best. Probably best to ask a scholar if you're STILL confused.
Found this lecture about faith btw,
