The Universe Has Always Been a Singular Phenomenon, and Forever It Shall Remain So

Most of us have wondered: "What existed before the Big Bang, or what was the phenomenon affected by the event itself?" As I ponder this question, inductive ideas begin to form in my mind.
For instance, if you have researched Islam even slightly, you know that God is defined as Al-Wahid, meaning "The One and Only." I considered merging this concept with the hypothesis of a cyclical universe—an endless cycle of existence and annihilation. That is to say, I refer to a cyclical hypothesis where, since time immemorial, the destruction of one cosmic formation triggers the birth of another.
Then another thought occurred to me: Do not the Quran and authentic Hadiths mention that God created eighty thousand realms beyond this universe, each distinct from one another? Reflecting on this, a question emerged: As one universe perishes and another emerges, is there no progression taking place?
Later, I was reminded of the verse in the Quran, "We have created humanity superior to seven universes." I then pondered the diverse characteristics with which people are endowed and asked: "Could it be that our traits in this current universe are a result of our deeds in the universe before it?"
In other words, if all human beings were created under equal conditions in the very first of these sequential universes, and if each individual subsequently shaped their future traits in successive universes through their own conduct, then—even if unperceived—we have all been filtered down to this present state from origins of absolute equality. Consequently, no human being holds the right to complain about their present circumstances.
Furthermore, if we possessed a deeper understanding of the Quran, perhaps we could unlock vast realms of knowledge beyond our current reach.
