Some people do not believe in God. As for some of those who say that they believe in God, they may, without realizing it, draw close to associating partners with God through various thoughts and actions. This truth is revealed in the Qur'an as follows: “And most of them believe in God only when they can attribute partners (to Him).” (Surah Yusuf, 106) Associating partners with God is not limited merely to turning to idols, as most people think. Its real danger lies in failing to comprehend, as one ought, God's absolute power, sovereignty, and His uniqueness in creation. https://www.harunyahya.info/en/articles/associating-partners-with-god-is-a-disease-of-the-soul
