‘Shirk’ comes from the Arabic root (S-R-K) with the general meaning “to share”.

The most important statement of belief is faith in greatly respecting Allah, one GOD. Something opposite to that is known as stay away from or associating partners with Allah. This is often understood/explained as loving more than one God, Shirk.
Act of Shirk includes failing to serve God, denying His Existence, and sharing or associating a partner with Him, whether the partner is a predictor of the future, an idol, the sun, the moon, or any other being or thing. Serving and praising deities other than Allah, who have no power to benefit or harm, is an act of injustice to serving to Allah — who created this whole Universe and gave life to you and me. Shirk is the one inexcusable sin to Allah:

“Surely Allah does not forgive that anything should be associated with him and forgives what is besides that to whomsoever He pleases, and whoever associates anything with Allah, he devises indeed a great sin.” (4:48).
“Surely whoever associates (others) with Allah, then Allah has forbidden to him the garden, and his abode is the fire; and there shall be no helpers for the unjust.” (5:72).
‘Shirk’ is invoking or praying to other (deities) besides Allah. Almighty Allah says: “And when they embark on ships they invoke Allah, making their faith pure for him only, but when he brings them safely to land, behold, they give a share to their service to others (29:65).”
‘Shirk’ is rendering obedience to any authority against the order of Allah. Almighty Allah says, “They took their rabbis and their monks to be their lords besides (Allah) by obeying them in things which they made lawfully or unlawfully according to their desires without being ordered by Allah and they also took their lord (Messiah) son of (Maryam) while they were commanded (in the Torah & Gospel) to worship none but one (Allah).”(9:31)

Begging for, or petitioning, direction and insurance, and so on for help, from others than Allah; accepting that items have “abilities” of mending or best of luck,(without any concern about/having nothing to do with) whether that article incorporates Quranic composing or some other Islamic Searching for and then finding your (desire to do something/reason for doing something) in life from material (occasions of chasing after something or trying to complete something), wanting and expecting for some different option from Allah; Exactly following (orders) others over Allah; showing that you are prepared to fight against Allah’s direction when it suits you Beginning/working at interesting/exciting (thing), magic or fortune advising that tries to see the covered up or (show/represent a potential future occasion) future occasions just Allah knows things like this What the Quran Says
” Say, “Invoke those you claim [as deities] besides Allah.” They do not possess an atom’s weight [of ability] in the heavens or on the earth, and they do not have therein any partnership [with Him], nor is there for Him from among them any assistant.” (34:22)

“And whoever associates anything with Allah, he devises indeed a great sin.” (Surah an-Nisa’ 4:48).
“And “serve” Allah and do not associate anything with Him.” (Surah an-Nisa’ 4:36).

Keep in mind everything belongs to Allah, All is from Allah.” (Surah an-Nisa’ 4:78).
