Culture as such is the way we as a group of people do things, our parties, celebrations and events. This can be good or it can be bad, sometimes in line with our Holy Quran and sometimes not. What is dangerous is when we mix culture and our Deen.
Allah have given us the Holy Quran as guidance for our spiritual and mundane life, He has clearly stated in the Quran that It is fully detailed and that anything we need to achieve a life as Allah want us to live is found there.
So if you add all kind of practices to the simple way of life outlined in the Quran, you are doing shirk, plain and simple. This is because you add to Allahs Deen. So all practices in connection to our Deen MUST be found in the Holy Quran, if not it has NOTHING to do with our Deen.
You may argue that how shall we perform all our Muslim practices and rituals that we do as Muslims if they are not found in the Quran? The answer is very simple, we do not do them!
The above statement will freak out the majority of todays Muslims. Why?? Because their RELIGION has endless practices not found in the Quran. So where do they find the basis for all these practices? They find them in the practices of their family, tribe or religion. Many of these practices are also found in the Hadith collections.
39:23 “Allah has sent down the best narration, a Scripture that is similar with two paths. The skins of those who reverence their Lord shiver from it, then their skins and their hearts soften up to the remembrance of Allah. Such is Allah’s guidance; He guides with it whoever He wills. And for whomever Allah misguides, then none can guide him”.
So, if you want to live as Allah wants you, please try to study the Quran. Unfortunatly so many translations are biased towards cultural input and Hadiths, so it is not easy to find a translation pure and correct. Still I hope in time more people will translate the Quran correct and also that all that call themselves Muslims will belong to the Deen of Allah, not continue being Sunni Muslims, Shiah Muslims, and any of the sects created.
Allah urges us to read, to study and verify everything for ourselves, not blindly following our parents, groups, imams and Hadith collections.
17:36 “And do not uphold what you have no knowledge of. For the hearing, eye-sight, and mind, all these you are responsible for”.
2:170 “And if they are told: “Follow what Allah has sent down, “they say: “No, we will follow what we found our fathers doing!” What if their fathers did not understand anything and were not guided?”
3:138 “This is a clarification for the people and a reminder for the righteous”.
