Is the saying of some common people, "So-and-so [vulgar word]," when something falls from their hand, considered shirk (polytheism), even though they may not be seeking help when they say that?

If the word uttered by common people is a call to a creature with the intention of seeking help, then this is major Shirk (polytheism) that Allah will not forgive, because Allah alone is the Helper and the Responder. However, if a person utters it by mistake or forgetfulness without the intention of seeking help, then he is excused, according to the saying of the Prophet, peace and blessings be upon him: "Indeed, Allah has pardoned for my Ummah their mistakes, their forgetfulness, and what they are coerced into." He must, however, be aware of the seriousness of the matter and not return to it, and seek Allah's forgiveness, and remember the importance of guarding the tongue.
