Yes, all humans possess a monotheistic nature that may change under the influence of environment and upbringing, yet no one can escape it.
The Holy Quran refers to the monotheistic nature of human beings. In Surah Ar-Rum, verse 30, Allah says, 'So set your face toward the religion, inclining to truth. And adhere to the fitrah of Allah upon which He has created all people.' This verse reminds us that Allah has created humans with an innate nature filled with monotheism and servitude to Him. Additionally, in Surah Al-A'raf, verse 172, Allah refers to the covenants made with humans in the realm of souls. This verse indicates that within every human being lies a tendency to worship God, and no one can escape this truth. This monotheistic nature of humans can be influenced by environment and family upbringing, but ultimately every individual can return to their inner nature. For example, some people may stray from religion throughout their lives, but in times of difficulty and life challenges, they may remember Allah and seek Him out. Therefore, we can conclude that the monotheistic nature is inherent in every human being, and they are in pursuit of finding God and establishing a connection with Him.
So set your face toward the religion, inclining to truth. And adhere to the fitrah of Allah upon which He has created all people.
And [mention] when your Lord brought forth from the Children of Adam their descendants and made them testify of themselves, 'Am I not your Lord?' They said, 'Yes, we have testified.'
On a beautiful day, Aref decided to immerse himself in nature, observing the trees and flowers in peace. He remembered the words of the Quran and thought about how human nature is inclined towards God and monotheism. Aref prayed in his heart and recalled Allah, feeling an incredible sense of joy. This day reminded him that life without the remembrance of God is meaningless and that humans are always in search of their monotheistic nature.
