Does a person become an infidel or a polytheist due to fear that vanishes when the light is turned on, or due to feigning sleep while walking to deceive the father into thinking one is asleep, or by pretending to be asleep out of fear of the father? And is saying "my penis's organic devil" after repentance considered polytheism with God, knowing that God is the Creator of all things?

Fear of turning on the light is not considered shirk (definition) (polytheism) or kufr (disbelief); rather, it is a natural fear. Fear is divided into three categories: The first is the fear of deification and worship, which is major shirk if the fear is directed towards other than Allah. The second is natural fear stemming from apparent causes such as enemies or animals, and this does not contradict faith. The third is illusory fear that has no basis or a weak basis, and this is blameworthy and causes its possessor to be described as cowardly. Therefore, there is no need to worry, and one should turn away from obsessive whispers.
