عقيدة التوحيد في القرآن الكريم وأثرها في البناء الإنساني

This study aims to prove the importance of monotheism belief in the Holy Qurʾān as a foundation for the construction of man in general and human personality in all its mental, physical, psychological and spiritual aspects, in specific. It portrays how Islam alone can build “human civilisation” because it is divine guidance from the Creator Himself. In terms of research methodology, the researcher will mainly depend on a descriptive approach and will also rely on an inductive approach to track the texts that prove this belief. Next, these texts will be analysed using the analytical method to obtain the results. This study will find the Qur’anic verses, relevant instructions and sermons to achieve this goal. One of the most important results reached by the researcher is that the Islamic doctrine can build a balanced, integrated structure of the human personality, and this personality will lead to happiness and a balanced perspective – away from racism and intolerance. People having personalities accept and love others regardless of their colour, gender, or race. There is no doubt the positive effects of monotheism and many religious approaches in building human personality. Perhaps the most important effects are tranquillity and contentment with God’s decree. Tranquillity is a dire quality needed by humankind today – tranquillity means a person feels at peace in their heart, soul, and mind, and there is no way despair can seep into his heart.
