Agreed, Quran is the book of guidance. But don't take out الهادى from the equation. Allah comes first, only he gives us the توفيق to read and follow Quran to it fullest.
Yeah, all this talk is great but like I previously mentioned it's just zubani kalami i.e lip service when in reality you follow man made made books. 95% of your beliefs, laws, religious practices and rituals come from these books. Name one thing you do which is from the Quran and is done as mentioned in the Quran without any addition from your side?
And this is for sake of argument these rituals are what you believe them to be
Salah : No five times mentioned, no rakats mentioned, no number of sujoods mentioned, no mention of your tashahud, no mention of what to recite in what position. No salams, no finger lifting
Hajj : No 7 times tawaf mentioned, no stoning of the devil worshiped, no running 7 times between mina and marwah, no muzdalifah etc etc. Technically even Mecca not mentioned
Fasting : Opening and breaking of fast times totally different, no comprehensive list of conditions because of which a fasts breaks, vomiting, bleeding etc etc
Zakat : No percentage of zakat given and when and how many times to give.
Shahada : No such thing in the Quran nor does it states one has to say this to become a muslim.
So even just looking at you self concocted 5 pillars of Islam, not a single one of them is done according to how Allah says they are to be done and performed according to your understanding.
Then if we just scratch the surface a little more there are beliefs are rituals you believe and follow that are totally alien to the Quran. Like your belief in return of Isa, Mahdi, Dajjal. Practice of tawassul, ehsaal el swab and circumcision,
Allah's word is never enough for you, so you look at manmade stories to expand your beliefs and practices
So yeah all this talk about believing in Allah and following his commands is just lip service. When in reality you follow the religion of man made books. Only the blind cannot see that the religion they are following is not from Allah, but rather a very wicked and ugly distortion of it.
