Welcome to the forum.
Islam has nothing to do with the religions that are about including traditional Islam.
Islam is with GOD not from GOD. This in itself indicate that everything created by GOD has to obey GOD s system and laws and we also obey whether we choose the obedience or disobedience- free will- (Tawan or Karhan).
So Islam to GOD is a state of mind followed by a way of life.
Qoran is not a book for just" Traditional Muslims", It is a book for all the humans. Al Naas No need to change into religions of Men. One can be a Muslim to GOD in any religion, by obeying and following GOD Alone.
Let me give the example of Moses and the cow in an analogy about religions of men
Moses said to his people to sacrifice-Idhbahu- a cow.( He did not say The cow .i.e no specification , knowing there will be questions to follow)
His people obviously thought what type of cow to which Moses answered I am not ignorant- i.e I have knowledge about this type of cow-
So they asked the questions
1- What type. A= Neither old nor very young. In between the two.
2_ What colour A= Yellow - A striking colour that lets everyone know its state just by looking at it.
3_Give us some additional details to know for sure A= A cow full of itself/confident... that does not till the earth/prepares the ground nor does it water it, Appears peaceful/good-Musallamatun- and does not benefit anyone or anything.
So they obeyed with reluctance/fear of what becomes of them./consequences from people...
Our benefit from this story can be a general lesson to all the generations regardless of time and place
Moses is asking all of us to dissect our religion_ a cow- as each party has different religions - _Idhbahu is not Uktulu, the difference is the first one you benefit from it- in other words check your religion by dissecting it to understand it using your faculties that GOD gave you . Ask the questions
1- Are we following the old or the very new blindly and mixing . i.e pick the best from both through your effort with your faculties and reasons. Following either blindly must be avoided.
2_ This religion of ours could be ill - Its yellow colour shows its state-and others see it as such by just looking at our ways.Do we clearly see flaws in a religion and still follow by ignoring our instinct.
3-This religion looks like it is preparing us but in fact it has no life The people look confident with it but gain nothing from it. So dissect such a religion and only pick the things that agree with GOD s message.
Otherwise we are killing our spiritual self. Dissecting it will result in its resurrection with GOD s obedience and guidance.
GOD bless you.
Peace.
