Celestial World as Introduced in the Holy Quran and the Effects of Belief in Its Reality

One of the Quranic teachings that we are familiar with is the existence of spiritual realms for the universe called celestial worlds. Based on this theory, analysts of the celestial world believe in a heavenly phase for every creature. Through lexicographers’, sages’, and Gnostics’ viewpoints and based on Biblical interpretations and traditions we have come up with the idea that the celestial world is the true nature of the universe encircled by God in such a way that all beings act in the right way due the divinity and mightiness of God. Thus it is an indication that this world is comprehensible and that the most thorough way to reach an understanding of the world is through thinking and acting simultaneously. From an ontological point of view, celestial worlds are worlds involving the spirits of beings in the actual world with different ranks. The present paper’s main concern is the possibility of comprehending the nature of this Quranic teaching, its proof, its clarification, the necessity of believing in it and its effects on human beings – insightful effects, perfection, and ethical tendencies.
