According to the Quran people who claim to be muslims religion-wise are not muslims at all. It is because islam is not a religion rather it is a purpose based proper way of life, it is a purpose based proper rule of law and it is a purpose based proper governing system for humanity from God so that they could bring about and maintain a purpose based proper human community according to it in a place in his kingdom for their own blissful, dignified and secure state of existence through help and full support of each other by complementing each other purposefully properly.
So according to the Quran Muslims are only and only those people who are purposefully properly and wholeheartedly committed, dedicated and devoted to working for the purpose of unity, peace, progress and prosperity of mankind.
Baseless and unfounded harmful and destructive beliefs and practices have nothing at all to do with actual islam because they only and only waste time of people as well as put them at odds with each other.
Money lenders and users as well as mullahs and their slaves are only and only stooges of front men of actual rulers who confuse and make fools of masses so that people become and remain their slaves. Therefore stop promoting falsehood in the name of God or be ready to suffer more and more by hands of each other. It is because if people will not prepare themselves purposefully properly for seeking, receiving, studying, accepting and acting upon purpose based proper guidance of their creator and sustainer purposefully properly then they will only and only believe and do what is in conflict with and contrary to actual islam. The consequences for ignoring the actual message of God are most serious for humanity.
