Definition Of Shirk
These are all form of Shirk which you mentioned. Knowingly means, in your heart, your fitra warns you against it, but man tends to ignore or pay heed to it. His behavior will determine his fate on the DOJ. Yes, there may be one, who sincerely commits shirk by making partners with God in His Being or with His attributes, as we find in the case of the Christians whose case will be talked about by God with Messiah on the DOJ as mentioned at the end of Sura Maida, Ch. 5. They may have excuse on the basis of their sincerity. This is what to be decided by God, not by Us, we know only the principles, and their applications is the prerogative of God.
